Waited on tarmac for approximately 15-25 minutes before taking off. When landing, the time it took to taxi to our gate was the also 15-25 minutes.

Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

It was good flight was smooth, little cold on the plane but other wise good.

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

The guy in front of me was talking constantly, even when the pilot was making announcements. I found this very disrespectful to the pilot and to others.

We left 1.5 hours late due to a “maintenance” issue. Very poor communication as to when we would board & depart. The crew in First Class was uncharacteristically not friendly). Delay into Brussels cost me my connection to Rome so lost the entire first day of vacation ( had a 10:30am flight to Rome - ended up on a 6:55pm flight).

Everything was OK except the meals, that was overpriced chicken meat.

Miss My connection I had to take a flight from Indianapolis to Denver , then to san fransisco , sleep in sans fransisco en the flight to Los Cabos the next morning

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

The flight was delayed instead of leaving at 11 it left at 12.20
