JetBlue Overweight bag fee can be a bit tricky, so let's break it down! JetBlue charges a flat fee of $150 for any checked bag that weighs between 51 and 99 pounds, regardless of the number of checked bags you have. This fee applies to both domestic and transatlantic flights. If your bag is slightly overweight, say 51-55 pounds, you might be able to avoid the fee by repacking at the airport or moving some items to a carry-on bag. However, for bags exceeding 55 pounds, the $150 fee is unavoidable. Remember, oversized bags (exceeding 63-80 inches) incur a separate fee, so be mindful of both weight and dimensions when packing your JetBlue suitcase.
