It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

2.0 MediocreFelipe, Jun 2024DTW - SAN

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The boarding was horrible. You couldn’t hear the announcements at all. Probably because there is so much in the area for businesses. They need a louder PA system. Other than that it was a good Delta experience.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

The A330-200 was showing its age but otherwise this was a pleasant flight with friendly crew. The meals/snack provided were pretty good.

This flight was supposed to land at 10:55 pm on January 14th. Instead, it landed at 3:20 am on Monday, January 15th, resulting in a completely lost day due to not going to bed until 5:00 am.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

Too many fees (but that seems to apply to all airlines nowadays)

It was delayed several hours which delayed our connection in Denver. Not happy.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Equipment swap led to 2+ hour delay on international flight. And to top it off, boarding took forever.

Wretched scheduling - they got themselves into a critical crew situation and didn’t try to address it until 15 minutes before they had to cancel my flight

They cancelled two flight and got us onto another airline, which was also delayed.

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

This plane is my favorite despite the very limited overhead space. Seats are comfortable!

It was great. It was just a commuter so I splurged on first class and it was wonderful. Wish all seats were this spacious. Enjoyed it and will do it again.

It was super hot. The flight attendant seemed forgetful and abrupt.

Deicing in Denver took forever and I almost missed my connection. De-ice faster! Not Americans fault.

3.5 hour delay!!! No plane for hours, mechanical issues and poor communication from airline. Horrible! Supposed to land at 8:54, landed at 12:32!
