Awesome service

Flight attendants service was absolutely fine, but there sure didn't seem to be the usual friendly engaging helpful smiles I'm used to on most flights.

Would be nice to have first checked bag free, especially smaller bag.

The open snack bar is a nice idea

The seats on an otherwise modern and updated plane weren't very comfortable after a few hours, and felt cramped. And charging $70 for two checked items is pretty bonkers.
