Okay. The wifi kept going in and out. The boarding process continues to suck, like all airlines I think. Still miss the orderly boarding before the changes.

I liked how easygoing everyone was and in tuned to detail. I especially loved how the flight attendants did what they could to help some parents keep their children calm and safe the entire flight. That meant a lot.

The flight was late, boarding took longer than it should have, it’s not offered anything to drink, and in Flight entertainment options were limited
