Heathrow has good signage. There are lots of people going to the same terminal waiting for the train. Be patient and when you have connecting flights choose a 2-hour layover.

Try to avoid Heathrow! Not the most convenient to get into London unless you have a driver. Also, Heathrow needs better signs on where to go to exit and better wifi for foreign travelers.

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Empty seats next to me - wish it had been for a longer flight!!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

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.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

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

The Polaris experience is top notch. From departure lounge to arrival lounge. Everything was top notch. One of the best first class experience

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average,

It started well but flight was cancelled and they created a nightmare rebooking. It is two days later and we still haven’t reached our destination. I am in Amsterdam waiting on transfer desk to open (later than other airlines) to hopefully get a boarding pass. Once that problem is solved we will just pray this flight isn’t cancelled too.

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

The United Airlines crew that operated this flight was subpar. They didn’t

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

Did not fly HOU to SAT as flight was cancelled.

Flight crew was among the best I’ve ever seen

Boing 747-8’s are showing their age. The seat back screens are somewhat unresponsive. Even putting the seat “in its original and upright position” required assistance from the guy behind me-after I helped the lady in front of me! I left a ball cap on board. I’ll be flying back in four weeks. I wonder if Lufthansa has a list a found for that kind of stuff in Frankfurt?

I liked that the chairs don't go back too far. I did not like the entertainment system, which was really terrible by industry standards. The crew were unpleasant. The main meal was terrible, the morning meal was quite good.

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

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.

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.

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

Horrible experience. They lost my luggage and still can’t find it. The plane ride was below average. Food also terrible compared to other airlines.

The team/crew were excellent. The USB ports were not working/broken, I tried multiple ports and also asked a staff member to check other ports on the flight, she confirmed they were not working!

It was good but my seat was terrible for a long trip, too small

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.

The flight itself was great… the only problem for me was the flight delayed both departure & connection.. instead of the 26 hrs (long enough) was an additional 4 hours more that took an aim to my body..other than that I’m pleased.

Had to cancel flight due to war in the Middle East, no refund, and insurance wouldn’t cover it!
