JetBlue has introduced a new peak and off-peak pricing system for checked bags. Under this policy, the fees for the first checked bag will vary based on the travel period. During peak times, such as holidays and busy travel seasons, the first checked bag will cost between $40 and $50, while during off-peak times, the fee will be $35. Additionally, passengers can save $10 per bag if they prepay at least 24 hours before departure [[❞]](https://onemileatatime.com/news/jetblue-raises-checked-bag-fees/) .
