Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

Awful. No counter attendants. No dinner offered due to delays.

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...
