On Jet2.com in 2026, the cost of a 22kg checked bag is not a flat fee; it is dynamic and depends on your destination and when you book. Typically, if you book online in advance, a 22kg bag costs between £25 and £50 per flight. A supportive peer "sticker shock" warning: if you wait until you get to the airport to add a bag, the price can skyrocket to £60 or more. Jet2 is famous for its generous 22kg limit (higher than the 20kg industry standard), but they are very strict about it. If your bag exceeds 22kg, you will be charged an "excess baggage" fee of approximately £12 per kilogram. If you are traveling as a group in 2026, remember that Jet2 allows you to "pool" your baggage weight, meaning if one person has a 20kg bag and another has 24kg, you won't be charged extra as long as the total for the two bags stays under 44kg and no single bag exceeds 32kg for safety reasons.
