Air Transat

Air Transat permits 1 personal item per passenger, in addition to your standard carry‑on, that must fit under the seat ahead. Use a safe maximum size of 43 × 33 × 16 cm (17 × 13 × 6 in); there is no official weight limit for the personal item. A second personal item isn’t sold—extra or oversized pieces must be checked instead, with fees typically starting at $50 USD when paid online (higher at the airport).

Air Transat permits 1 carry-on bag + 1 personal item per passenger. The carry-on must weigh no more than 10 kg (22 lb) and measure up to 23 x 40 x 51 cm (9 x 16 x 20 in) including wheels and handles; the personal item must fit under the seat. Extra carry-on bags are not sold—any additional cabin bag must be checked, with airport checked-bag fees typically from USD $50 each way (varies by route/fare).

Air Transat’s checked baggage uses the piece concept: most economy fares include 1 bag up to 23 kg (50 lb) and 158 cm (62 in) total linear dimensions; an additional bag purchased online typically costs $75 USD each way.
