Jetblue has become our new favorite airline! I like Southwest, but with Jetblue we can use the closest airport to us and we get to pick our seats in advance and not worry about checking in at 24 hours and/or purchasing early checkin. Southwest does allow you to change flights without incurring a change fee, though.
You can check in on jetblue.com 24 hours before your flight and print boarding passes. There is also a Jetblue iphone app that allows you to check in on your phone and the boarding pass is on your phone. There may be an android app, but I am not sure.
Each seat has its own TV. Bring your own headsets. Any headset that can fit into an iPhone, cell phone, etc will work. My kids thought it was so awesome to have their own TV. There are movies for rent, also. Jetblue is starting to put WiFi on their planes.
Non alcoholic drinks and snacks are complimentary. Here is the list of snacks.
PopCorners Popcorn Chips
Terra Blues Potato Chips
Linden's Chocolate Chip Cookies
Stauffer's Animal Crackers
King Nut Fancy Nut Mix
Fritos Original Corn Chips
Seats are comfortable (for airline seats) and each passenger gets one check in bag and one carry on bag complimentary.
Enjoy your trip!
