The plane itself was filthy. I had used masks in my seat back compartment and grease from someone’s head all over my window. I asked for wipes to sanitize the window and was told they didn’t have any. Then we landed at DC and the screen didn’t have a baggage claim for our flight so we all just waited around. After about an hour or so, someone asked an employee where all of our luggage was to which she replied “the back office, you need to show us your luggage number and pick it up that way”. No one had known that,

Wi-Fi did not work. There was no device from the airline to view news or entertainment programming Food was just a packet of bus off. For 2.5 hour flight in the morning, the breakfast substation was meager. It took quite a bit of time to check in as there were two agents, one was on hold over phone. We just made it in time at the gate in spite of being at the airport for two hours before boarding. Very poor agent interaction. Connecting flight time was also very tight, we could have missed it.
