As mentioned earlier I fly all the time for work, and I love SW/Jetblue. I rarely get to fly jetblue for a number of reasons but when I do I've got zero complaints. Shit all the seats have fucking tv/usb outlet. Delta and the other major ass-pile airlines(which I do sadly fly) don't even have that shit unless you are going international.
And as far as SW. I used to ONLY fly SW. I love that airline. Literally the best customer service I've experienced in my 10+ years of work travel plus the perks are awesome.
-Their Wifi works, is cheap and if you are a milage flyer it's free. Again the "top" airlines don't offer this. They have that fucking "gogo" bullshit which I can never get to work correctly and they do not offer it free to any tier of frequent flyer
-Best customer service. No fees or crap or standbys and flight changes.
-Usually funny and polite steward folks
-The boarding process is a bit fucked, particularly for people who have not flown in a while and don't understand the way it works. I don't mind cause I'm always A1-15 but I can understand the complaints here
-I have for many years in a row now got a "companion pass" which means on any flight I take someone can fly with me for free. Sadly I almost never use this thing, but it would be awesome if you had a wife/girlfriend that could travel with you
Only shitty part is they operate a single air plane model and have few direct flights to most places unless you do an east coast run
I recently moved out west and they just kind of suck now for me. I randomly selected Delta as my new airline a few years ago just because all of my fucking options sucked and it's better to stick with one for the mile perks. Delta can fucking blow me. I'm platinum and I still get treated like a sack of shit. Only noteworthy perk is the sky club
