I just took two Air Whiskey flights from ABE to ORD and return. Outbound right on time, drinks and snack mix served along with mints as we departed. Coming back there was a problem with an unescorted minor (no paperwork) that made us about 20 minutes late in departing. Pilot informed all about reason after airborne and said would make up time. We arrived ten minutes late. Again snacks, drinks and mints. FA much nicer and more professional than Mesa, so if that is an indication welcome to US. I would note they still aren't like PSA FA--but many of them were mainline previously--their still my express carrier of choice. (This is the flight I sat across from Mesa pilot who flew ABE to PHL regularly. He was looking forward to flying for Mesa out of ORD--but more important he has an offer to fly for SWA and will get out of express flying)
