JetBlue and Southwest are my top two. That's the case for me. I mean, free checked bags (One free bag for Jetblue, but two for Southwest as long as all of your checked bags are under 50 lbs.), free snacks and drinks, comfy leather seats on both but no assigned seats on Southwest. I hate those big airlines in the US. I don't understand why so many people have loyalties to those brands! They charge a lot for checked baggage, give you subpar airline food if you're crazy enough to buy it, lose luggage constantly and I don't even want to think about their sub-par safety records! But I hate United (My family flew all the time on Continental before the merger and I still hated their airline back then!), Delta, American and I'll add Spirit as well because I heard of awful reviews of their service even before logging on! I know the airline options vary depending on where you live (Being from NJ, my family typically flys out of Newark, though we've done Philadelphia International a couple of times.) and it's ultimately your decision to choose and you probably based it on money, non-stop flight availability, time and whatnot. But considering how much beef I have airport security, unruly passengers and everything, flying is the last mode of transportation for the time being.
