No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

I am a die hard Delta flyer, but they missed it on this flight. It was on their very dated 717-200 aircraft, which I knew when I booked it so I knew it wouldn’t have seatback screens. However, the internet was awful and it wouldn’t even send texts a lot of the time, much less even connect to the delta app. It was also very hot while in the air, which never happens. What was even more disappointing is that the crew only gave me cheezits and a beverage, even though I was in Delta Comfort. The main cabin fare gets these items. I didn’t get any kind of improved snacks and that was unacceptable. The crew wasn’t very visible at all either. If this was my first delta flight, it would be my last. I am just going to assume it was a one-off flight.

flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

We departed and landed early which was a nice surprise. The boarding process was slow.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

The WiFi was not working. That made for a long flight.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Check in at the desk was very slow pus Security, although not Virgin issue at JFK was a nightmare. 50 minuet wait no time to explore airport and get last minuet gifts. total wait 1.5hours

Great staff great experience, made a 2 hour delay very bearable

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

The crew was very good. However, the equipment was a bit dated. Some of the electronics were not working. To top it, three bags didn’t arrive with me. Two of them were delivered a day later. I’m still waiting for the third bag, I was so looking forward to this virgin Atlantic flight, but, I am disappointed.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

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.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

The plane was dirty and the in seat air wasn't blowing as planes usually do.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

The flight I booked was conveniently timed, had one brief stop and was going to be quick. The flight I ended up getting was delayed, took longer, had a far longer layover and arrived hours later than planned. Thanks for nothing.

Bad experience going to DFW with an IT outage then bad on the way back with a nearly 5 hour delay that’s started as maintenance then caused us to wait further due to weather - which would not have happened if we had left on time.

Horrible experience flying with American. Flight was delayed due to inbound flight delay. Fine, it happens. Then, we were delayed an additional almost 30 minutes due to the paperwork for departure having a "clerical error." Then, upon landing at the destination airport we were stuck on the plane for an HOUR after we landed and pulled up to the gate because apparently there was another plane. An hour waiting for the gate 12:30 AM when the flight has already been delayed due to operational error feels like a complete failure of the ability to do the one thing they need to do apart from actually have the plane takeoff and land. Very disappointing.

It was a 3 hour flight from Dallas to Missoula. The aircraft did not have power plugs, internet or in-flight entertainment. When boarding, one flight attendant was "somewhere in the airport" so delayed the boarding process (not coming from another flight) although we did take off on time and landed early. In flight there was little to no service - we got the standard beverage but no real connection with the crew which feels unusual for a 3 hour flight. A passenger needed help stowing her bag and got no assistance, and actually some passive aggressive comments from the flight attendants about "she needs to remove the extender" and "she'll have to find a place for it". I have seen others be helpful and put a bag in the closet, or support assistance as the boarding door was already closed. Just not a great experience considering the cost of my round trip ticket {$1000}.

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

My first time flying American Airlines, my first flight to CLT was wonderful and flight attendants was nice and had great customer service. My second flight from CLT to NY was very delayed due to whatever reason the crew was not greeting other than that I’m rate 8 .

A 50 minutes flight that is delayed over 90 minutes kills every connection, thank you American Airlines

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

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

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

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

Surly rude flight attendants. I ordered the chicken and was given a vegetarian meal with no explanation and no opportunity to change it. I tried to order another beverage and was told by the young humorless flight attendant to “wait”. And she never came back. The seats were very uncomfortable and cramped. The last time I flew British Airways was many years ago but I remember it was amazing and the crew were very charming. This was a terrible disappointment given the cost of the flight.
