Just a heads up.
24 long is too big for JetBlue unless they are empty. It will have to go in sid ways and if the flight is full they will gate check it to the carousel at your final destination.
There are very few airlines with overhead bins 24" deep anymore, and they frown upon bags going in sideways. Even SWA will growl at a 24" bag regardless of their board in the first pic.
If you're in the market I personally wouldn't purchase larger than a 20" to save any hassles.
Just based on my experience as a "very" regular flyer [emoji6]
