Oceanic Airlines.

Aegean Airlines, member of Star Alliance

Qatar, Emirates and Etihad are the best ones i have tried. SQ is also really good

Not United airlines.

Singapore airlines is the best in the Asia-Pacific region for me.

Spirit Airlines

Among the American ones, I've only used United, in 2013. It was great! Turkish Airlines remains unbothered tho.

I like the prices of Southwest but their aircraft is not-so-clean. I fly them short distance, major airlines long distance.

Most airlines nowadays have screen in every backseat and USB/portable charger. Hope southwest will have them soon.

Anyone ever flown Spirit, Allegiant and Frontier? I read their prices are affordable.

Lots of hidden fees (such as them charging to print boarding passes, I think carry-on luggage is charged etc)
Frontier has been having some sales for $15 tho lately so it might not be that bad.

carryons cost more than the ticket

but everything in consideration, you'll still come out ahead compared to other airlines.

Emirates/Etihad/etc

I fly with delta poor lessor companies l and it's great I fly for damn near free

United

United is under some investigation right now. Their customer service has been going downhill lately.
