The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Old plane and old configuration/seats but still comfortable for a morning flight

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

A little bit more leg room in premium economy. I am 6’4”.

Overall it was good. I missed my connection but I was put on another flight.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

in chicago, you have to go out to drop off your luggage for a connecting flight and come back into a security check. which was horrible with a government shut down. some airports you down off luggage and go to your gate. things were not cleanly marked.

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

We were delayed for a “couple of maintenance issues.” They were resolved rather quickly but a computer glitch caused someone in the airport to have to bring a physical copy of the paperwork so we could leave. I don’t know where they had to drive from to get to our plane but it took forever & we were 1 1/2 hrs late in leaving. The flight itself was fine.

We didn't take off until an hour after we boarded.

The flight was fine. This survey is not. There is no option for N/A so items which don’t apply to my experience still must be rated. In those instances I give a “3” rating which ultimately skews the results.

The actual trip was fine, however, the changes made to our flights and the layovers were had to endure were awful.

Flight from Dallas to OKC was good, but my trip was interrupted due to a delayed flight from Austin to DFW, which happens all the time. I frequently miss my connection from DFW and American can never seem to make this work!

Because the plane was 90 degrees F, they would not let us board. I wish they had, because it meant we were delayed. It's Texas, of course it's hot. We would have survived.

Wish they had the seat-back video screens for watching movies or playing games.

Excellent. Thanks to United Star Alliance, since economy was overbooked, I’m grateful to have been upgraded to Business Class.

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

Disaster. Downgraded. Zero apology. No effort or coordination between gate and crew. Awful seat blocked by door emergency slide box. Iberia is a mess. App never works. Avoid this airline.

We departed late but made up most of the time in flight. Our ticket was pure economy, so it wasn’t anything fancy; however, I heard that we arrived in Madrid at the exact same time that First Class passengers arrived! Overall, our experience was similar to what we had on other American Airlines transatlantic flights - good value at a reasonable price. We were even able to get our carry-on baggage onto the plane without needing to gate check it.

Flight was OK. Waiting for luggage in Madrid for 55 minutes, unacceptable

Transportation from gate to airplane was poor we stayed in hot bus for 20 minute no vantilation

The crew were friendly and helpful. Iberia lost our luggage on arrival, Friday and we didn't get it until Sunday at 10:00 p.m. local Malaga time. I also paid $382.80 for seat assignments but two out out of the four were not together. Iberia mentioned that it was because the plane was delayed in Madrid before our flight began in LAX. They should compensate us half of my payment.

We liked the flight but while we purchased an aisle seat, our seats had a different configuration on this flight. A fellow passenger suggested that the airplane had been changed. Too bad we were not informed and had no chance to modify our seat preferences. We were stuck in the window and middle seats with no chance to walk around and go to the bathroom without disturbing our sleeping fellow passenger.

Boarding an international flight via several sets of stairs and shuttle busses to the tarmac even when multiple jet-bridges were empty at Madrid airport (the hub for Iberia) was not pleasant. I was fine, but a lot of elderly folks and families with kids were struggling. A bad way to start a flight. Business class seats were nice, although not cleaned well from the prior flight.

The flight was great; I don't see any area of improvement.

No WiFi in either flight. No leg room, the seat in front of me left dents on my knees and the tray was so low my knees propped it up if I tried to use it.

It was a good experience, especially travelling with a baby and their accessories

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Didn’t fly with them as someone had cancelled my flight

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

Was delayed on first leg and missed connection. They would not let me board although I arrived at the gate 5 min before take off. I was delayed 24hrs

Very crowded, no real explanation of food "chicken or pasta?" After dinner no drinks service. Plane was clean, but little help with finding soaces fir luggage to get into overhead bins. Many passengers putting 2 bags, hats, duty free in overhead bins so no space for roll ons

bad, made it to connecting flight and they didnt let me board

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.
