Great food and good entertainment options for the long flight.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Good communication regarding any updates time of flight and flight delayed. The fight was delayed by two and half hours at eleventh hour. That was unexpected, especially when you international passenger.

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

Don't irreparably damage my luggage, don't stand around talking in the kitchen area of the plane when a passenger is waiting to speak to you, don't run out of a meal selection so have me end up eating bread for dinner. Lastly, regarding the code-share flight from DFW to JFK....STOP PARTNERING WITH AMERICAN AIRLINES - THEY ARE THE WORST AIRLINE IN THE WORLD! The delay, followed by another delay, followed by disorganized boarding, followed by stale snacks fit for a rodent, followed by a pilot who literally slammed the plane onto the runway when landing causing quite some concern among the passengers.

Food was great. Customer Service not so much! Flight Delays.

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Wonderful crew, good food. Absolutely loved the wine spritz and wish I could buy it!

Nothing, it was a fraudulent transaction. You probably should have caught that.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Business Class layout was excellent. The seats were not nearly as comfortable as UA, Delta or Air New Zealand (the best). Nor were the controls as flexible. Food was okay but not great. Breakfast pancakes were like cardboard.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The plane was comfortable but the crew wasn’t friendly.

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Got home at 3am after deboarding the plane. No compensation offered by American

Delayed 24 hours. Should have called it much earlier They provided quality accommodations, food vouchers etc. FINALLY The issues started at 8 AM and they cancelled the flight at 11:30 PM, with no plans for a new flight.

The flight attendants as well as the gate agent were out to lunch. Nothing extraordinary about their service. American just keeps getting worse every year.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Flight was a delayed a few minutes but nothing crazy, everything went extremely well

Our seats were better than i had anticipated. They provided nice pillows and blankets as well as a kit with ear plugs, sleep mask and headphones which made the long haul flight better. Their food selection and service was good. I appreciated that they came through the cabin with water a few times. We were ahead of schedule which was nice!
