There's a specific quality to the fifth day at sea on a transatlantic crossing. The last port is behind you. The next port is ahead. There's nothing in any direction but water and sky and the ship cutting through it all.
Some people find this intoxicating. Others find it isolating. Knowing which one you are before you book is the most important thing this guide can tell you.

What a Transatlantic Cruise Actually Is
The term covers two distinct products that often get conflated.
A direct ocean crossing: The ship's sole purpose is getting from one continent to the other. Queen Mary 2's classic route, New York to Southampton, is 7 nights of open Atlantic sailing with no intermediate ports. You board in America, you disembark in England, and between those two events is the ocean.
A repositioning cruise: A cruise line moves its ship from a winter homeport (usually the Caribbean or Florida) to a summer homeport (usually Europe) in spring, or the reverse in fall. These sailings typically run 12–16 nights, include 2–4 port stops along the way (often the Azores, Canary Islands, Bermuda, or Lisbon), and have 4–7 consecutive sea days crossing the Atlantic. They're priced to fill. Rates are often the best in cruising.
Both are real transatlantic crossings. They appeal to different travelers.
The Routes
New York to Southampton (and reverse)
Cruise Door Organizer 24 Pockets Magnetic
- 24 clear pockets attach magnetically to the metal cabin door
- Holds sunscreen, lanyards, snacks, and small items
The single most recommended cruise hack — turns your cabin door into instant storage
View on AmazonCunard's Queen Mary 2 has operated this route continuously since 2004. And before QM2, Cunard had been crossing this water since 1840. The crossing is 7 nights westbound (New York to Southampton) and 7 nights eastbound.
5-Pack Cruise Lanyards Waterproof
- Waterproof holders protect your cruise card at the pool and on excursions
- Five lanyards for the whole family
Your cruise card is your key, wallet, and ID — a waterproof lanyard keeps it safe and accessible
View on AmazonDistance: approximately 3,459 nautical miles.
QM2 departs New York from the Brooklyn Cruise Terminal and arrives at Southampton's Ocean Terminal, which connects to rail service for London (90 minutes).
The appeal here isn't primarily logistical. It's the ritual. Cunard has perfected the ocean crossing as a formal event. Gala evenings, the Chart Room bar, afternoon tea in the Queens Room, the Royal Arcade. There's a reason people cross on QM2 specifically rather than any other ship.
Florida/Caribbean to Europe (Repositioning, Eastbound)
April and May see a mass migration of ships from Miami, Fort Lauderdale, and Port Canaveral toward Barcelona, Rome (Civitavecchia), Lisbon, Amsterdam, and Copenhagen.
Typical ports of call on the crossing: Nassau or Bermuda as a final Caribbean stop, then a transatlantic stretch of 5–7 days, then arrival at the Azores (Ponta Delgada) or Canary Islands (Las Palmas) before Europe proper.
Total sailing time: 12–16 nights.
Lines operating spring repositioning: Royal Caribbean, Celebrity, Norwegian, MSC, Holland America, Princess, Carnival. Almost every major cruise line repositions ships in spring and fall.
Europe to South America / Caribbean (Less Common)
Some ships cross from Lisbon or Barcelona to Buenos Aires, Barbados, or Miami in late fall. November repositioning in the reverse direction. These are less common and more variable by year.
Mediterranean to North America (Fall Repositioning)
October and November bring ships back from European ports. Barcelona, Lisbon, and Rome see significant outbound traffic heading back to Fort Lauderdale, Miami, and New York.
The Ships Worth Knowing
Queen Mary 2 (Cunard)
Queen Mary 2 is purpose-built for ocean crossings in a way no other current ship can claim. She has a deeper draft and higher freeboard (hull height) than cruise ships designed for tropical markets, making her inherently more stable in open-ocean conditions.
What sets QM2 apart:
15 restaurants and bars, including the formal Britannia restaurant spanning two decks
Royal Court Theatre. West End-caliber productions
The only Cunard kennel program at sea (yes, you can bring your dog)
Canyon Ranch spa
Ballroom dancing program
Fully loaded enrichment: lectures from Royal Academy of Dramatic Arts, Illuminations planetarium
Cunard's fares run higher than repositioning alternatives. A 7-night crossing in a standard Britannia cabin typically runs $1,200–$2,500 per person, rising significantly in Grills-class suites. But the product is genuinely different from a repositioning sailing.
Mifaso Cruise-Approved Power Strip
- Cruise-approved (no surge protector) with multiple USB ports
- Compact design fits perfectly on the narrow cabin nightstand
Cruise cabins have limited outlets — this solves the charging problem without tripping ship safety rules
View on AmazonCelebrity Apex and Beyond (Eastbound Spring)
Celebrity's Edge-class ships reposition from the Caribbean to Europe in April–May. These are among the most design-forward ships at sea and carry a more sophisticated adult demographic. The enrichment and entertainment is legitimately good for long sea days.
DIYMAG Magnetic Hooks 6-Pack
- Super-strong neodymium magnets stick to cabin walls and ceilings
- Hang hats, bags, towels, and lanyards anywhere
Cruise cabin walls are steel — magnetic hooks turn every surface into storage
View on AmazonCelebrity's repositioning fares are competitive: $100–$160 per person per night for a balcony cabin during peak repositioning season is common.
Holland America Westbound (Fall)
Holland America runs fall repositioning sailings from Rotterdam, Amsterdam, and Copenhagen back to Fort Lauderdale. These tend to have enrichment programs well-suited to sea days: Lincoln Center Stage performances, America's Test Kitchen demonstrations, and BBC Earth content.
Norwegian and Royal Caribbean (Volume Operators)
Both lines reposition large ships in both directions annually. The onboard experience is more entertainment- and family-focused than Holland America or Celebrity, but the pricing can be exceptionally low. $70–$120 per person per night for inside or ocean-view cabins during early booking windows.
For the right traveler (doesn't care about enrichment, just wants the ocean crossing cheaply), Norwegian or Royal Caribbean repositioning is the best value in transatlantic cruising.
Sea Days: The Real Experience of a Transatlantic
This is what separates transatlantic cruisers from the rest: they must genuinely enjoy being on a ship.
On a typical Caribbean 7-night itinerary, you have one or two sea days. On a transatlantic crossing, you might have five or seven in a row. If you find sea days boring, this is the wrong trip.
If you find them restorative. Here's what they actually look like:
Morning: Fitness center at 7am before it fills. A slow breakfast in the main dining room with real coffee and a book. A lecture at 10am. Maybe on the history of the Atlantic crossing, or on the ports ahead, or a naturalist talking about seabirds.
Midday: The spa thermal suite on a rough-weather day. Lunch at the buffet or a casual venue. An afternoon trivia session if you want the social energy, or your deck chair if you don't.
Afternoon: The ship's library. Reading with the ocean outside the window. Tea service on Holland America or Cunard. A genuine ceremony, not a brochure point.
Evening: Getting dressed for dinner (the formality level varies by line. Cunard has actual black-tie nights; Norwegian has none). A show. Quiet drinks in a bar that doesn't have a DJ.
The passengers who love transatlantic crossings tend to be readers. People who have always wanted three days with no wifi and nothing urgent. People who want to think.
A transatlantic crossing is one of the few remaining contexts in modern life where being unreachable is the product, not the inconvenience.
The Repositioning Deal Strategy
Repositioning sailings are priced to fill ships that are literally in transit. The cruise line would rather have passengers than empty cabins on a journey it has to make anyway.
When to look:
Spring departures (April–May): Search from January to March. Best early-booking prices appear in January.
Fall departures (October–November): Search from July to September.
What to look for:
Per-night cost under $120 for a balcony cabin is very good
Per-night cost under $80 for an inside or ocean view cabin is exceptional
Some repositioning sailings include drink packages or free gratuities as booking incentives
The one-way logistics question:
You're traveling from one continent to another. You need to get home. The most elegant solution: book a one-way transatlantic cruise and a one-way flight in the other direction. New York to Southampton by ship in spring, London to New York by plane when you're ready to come home. Or Southampton to New York in fall, with a New York to London flight as your outbound.
This requires one-way airfare, which is sometimes (not always) more expensive than round-trip. Factor this in when evaluating whether a repositioning deal is genuinely as cheap as it looks.
Weather on the North Atlantic
Honest assessment: the North Atlantic is not the Caribbean.
Spring crossings (April–May) are variable. You can have four days of sunshine and two days of 15-foot swells. Sometimes the swells come first and the sunshine follows. Modern ships handle this well. You feel it, but QM2 in particular is engineered for exactly these conditions.
Fall crossings (October–November) tend to have more settled weather on westbound routes. The prevailing winds and currents run east to west, which makes westbound crossings (Europe to America) typically smoother than eastbound (America to Europe) in the same season.
If motion sickness is a genuine concern, see our cabin selection guide for motion sickness before booking your cabin.
Packing for a Transatlantic Crossing
The Atlantic in April is not the same temperature as the Caribbean in April. Pack accordingly.
What you need that you might not pack for a Caribbean cruise:
A proper warm layer — a fleece or light wool jacket for deck time. Even in May, the open Atlantic at night is cold.
At least one formal outfit if you're sailing on Cunard. On QM2, gala evenings are real, and dressing for them is part of the experience. Other lines are casual.
Extra books. You will read more than you think. E-readers are fine; a few physical books are better for some people.
Seasickness medication as a precaution, even if you've never been sick before. The North Atlantic in rough weather is different from the Caribbean.
What you can leave at home:
Snorkeling gear, beach gear, excessive casual clothing. Sea days have a rhythm — smart casual is the dominant mode on most ships.
Is a Transatlantic Cruise Right for You?
Aerotrunk Compression Packing Cubes 4-Pack
- Double-zipper compression cuts volume by up to 60%
- Four sizes cover every clothing type
Compression cubes are the single best way to fit a week of cruise outfits into a carry-on
View on AmazonHere's the honest filter:
You'll love it if:
You find sea days restorative, not boring
You genuinely enjoy the ritual of shipboard life: dressing for dinner, afternoon tea, evening shows
You want a genuine break from connectivity
You love the idea of arriving somewhere by sea rather than by air
You're looking for the best value per night in ocean cruising
It might not be right if:
You need a daily port stop to stay engaged
You're prone to motion sickness and haven't addressed it pharmacologically
You're traveling with young children (the sea-day-heavy format is genuinely hard with kids who want stimulation)
You're making a short trip and need to be back by a specific date (flights are more predictable)
Browse transatlantic ships to see what's crossing the Atlantic this season, or compare cruise lines to find which operators offer the best enrichment programs for long sea days.
The Atlantic is still there. The ships still cross it. And there is still something that happens between New York and Southampton that doesn't happen on a flight between those two cities — something worth considering at least once.
