What is Air Transat's carry-on bag size limit?

Air Transat allows one carry-on bag up to 51 × 40 × 20 cm in economy. This applies to all economy fare types including Eco, Eco Budget, and Option Plus.

How much can my carry-on weigh on Air Transat?

Air Transat sets a combined weight limit of 10 kg for your carry-on bag and personal item together in economy class. Each individual piece is not independently capped — it's the total that counts.

Does Air Transat Club Class get more carry-on?

Yes. Air Transat Club Class passengers are allowed two carry-on bags plus a personal item, with the same combined weight limit applying. This is a significant advantage over economy for business or luxury travellers.

Can I bring a personal item on Air Transat in addition to my carry-on?

Yes. Economy passengers may bring one carry-on bag (51×40×20 cm) plus one personal item such as a purse, laptop bag, or small backpack. The personal item must fit under the seat in front of you.

Does Air Transat enforce carry-on weight limits strictly?

Air Transat does enforce the 10 kg combined weight limit, though enforcement intensity varies by departure airport. Montreal and Toronto departures tend to be more thorough than smaller regional airports.

Air Transat Carry-On Rules: Size, Weight & Tips (2026)

Air Transat is Canada's largest leisure and charter airline, operating primarily transatlantic routes between Canada and Europe, as well as sun destination routes to the Caribbean and Mexico. Unlike budget carriers, Air Transat includes carry-on baggage in all economy fares — but the specific limits and some package-related gotchas are worth knowing before you fly.

Economy Carry-On Allowance

All Air Transat economy passengers — regardless of whether they've booked Eco Budget, standard Eco, or Option Plus — are entitled to:

One carry-on bag: maximum 51 × 40 × 20 cm
One personal item: purse, laptop bag, or small backpack that fits under the seat
Combined weight: 10 kg maximum for both items together

The 51 × 40 × 20 cm carry-on size is slightly smaller than the 55 × 40 × 20 cm standard used by many full-service carriers, so double-check your bag's dimensions. Many popular carry-on suitcases that fit on Air Canada may technically exceed Air Transat's limit.

Club Class Carry-On Allowance

Air Transat Club Class (their business class product on transatlantic routes) offers:

Two carry-on bags plus a personal item
Same combined weight limit applies
Priority boarding, which makes overhead bin space easier to secure

Two carry-on bags on a transatlantic flight is genuinely useful — you can separate work gear from essentials and keep both accessible during the flight.

The 10 kg Combined Weight Rule

The combined 10 kg rule is how Air Transat counts your cabin allowance. If your carry-on suitcase weighs 8 kg, your personal item can only weigh 2 kg. In practice, this means:

A fully packed carry-on suitcase leaves very little room for a laptop bag
Packing a laptop, charger, water bottle, and snacks in your personal item can easily push you to the limit
Weigh both bags together at home before you leave

Common Gotcha: Resort Package Bookings

Air Transat is heavily used for resort vacation packages to Cuba, Dominican Republic, Mexico, and other Caribbean destinations. Packages booked through Transat Holidays or TUI Canada may include different checked bag allowances depending on the bundle tier, but carry-on rules remain the same regardless of your package type.

A common mistake is assuming that a "full package" upgrade automatically increases the carry-on limit. It does not. If your resort package includes 2 × 23 kg checked bags, your cabin allowance is still 10 kg combined.

Another trap: on group charter departures for resort packages, check-in lines are often extremely long. Arriving with an oversized or overweight carry-on causes delays for everyone. Airport staff at resort-route counters (e.g., Montréal–Varadero) are typically thorough about checking bags before the rush.

How Air Transat Compares to Air Canada and WestJet

Carrier	Carry-On Size	Weight Limit	Personal Item
Air Transat	51 × 40 × 20 cm	10 kg combined	✓
Air Canada	55 × 23 × 40 cm	10 kg	✓ (5 kg)
WestJet	51 × 40 × 23 cm	No weight limit published	✓

Air Canada has a separate 5 kg weight limit for the personal item, making it slightly more flexible when you have a heavier laptop bag. WestJet does not publish a hard cabin bag weight limit for economy, which means less risk of being caught out at the gate — though staff do retain the right to check.

For size, Air Transat's 51 × 40 × 20 cm is notably narrower (20 cm depth) than WestJet's 23 cm. If you have a slightly puffier soft-sided suitcase, WestJet may be more forgiving.

Transatlantic Travel Tips

Flying transatlantic — typically 7–9 hours from Toronto or Montreal to European destinations — means the carry-on is your lifeline:

Pack a comfort kit in your personal item. Keep noise-cancelling headphones, an eye mask, lip balm, and a light layer accessible without opening your overhead bag.
Liquids in the carry-on, not the checked bag. Sunscreen and toiletries in a 1-litre bag should go in your carry-on, particularly if your checked bag is going directly to a hotel and you're clearing customs first.
Laptop and valuables always in the cabin. Air Transat's transatlantic routes check bags to the final destination, so laptops and cameras should stay with you.
Board early if you're in a middle group. Air Transat's overhead bins fill quickly on packed transatlantic flights. Check-in online and board as early as your group allows.
Weigh both bags at home. The 10 kg combined limit is easier to hit than most people expect on a 7–10 day trip.
