Reviews of the top 5 airlines flying from London to Colorado
Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress
Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress
First time flying with UA and it was a great experience. Thank you
Staff on board was excellent. Positive upbeat helpful- like it used to be.
United has come a long way, it’s been a fantastic experience traveling with them.
The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!
Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.
Cabin crew was very friendly, requests were satisfied promptly and cheerfully, and the cabin was reasonably clean when I boarded. The United lounges at Newark and Heathrow are always well-run and comfortable, especially Newark. I look forward to the new lounge that will be part of the rebuild of Terminal 2 at Heathrow.
The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.
I was lucky to sit in a seat with legroom in economy . The airplane felt like it was 100 years old, seats were very basic, barely reclined. Food was alright , staff was ok but not the friendliest. But all in all ok trip, perfectly on time
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 room where it was being kept.
Terrible flight. 1. They’ve only one option for food. 2. Seats are very cramped and screens are tiny 3. No pillow or blanket provided on long haul flight
Everything was better but france airlines more better than them
Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.
Too cramped up for the better seats I paid for.
I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.
Crew was enthusiastic. Meal was surprisingly good. They came to give water very frequently. Negative that the seat reclining didn't work
The boarding process would have been better. When people are flying internationally and the airline is a member of Star Alliance they cannot have different rules for carryon baggage. Brussels Airlines made us adjust the weight of our carryons based on their rules even though we were flying international and our next flight was with United which does not have weight restrictions for carryons. That was just ridiculous.
Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.
Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.
my husband's monitor did not work. there was a visibly ill family in my husband's row.
Let's just say I won't do it again.
How can the airline deploy the oldest 757-200 with a broken down entertainment system and no WiFi for a cross Atlantic 7:50 hr torture chamber experience?? My seat 3A couldn’t be reclined. The footrest was flimsy and useless. And there’s no leg support unlike their newer 737-Max which they lavish on intra-Europe routes. Shame!!
1. No food on a 8 hr flight is a travesty! The fare was not that low. 2. The entertainment was pretty bad and you had to buy headphones!!! 3. Only 2 toilets for the whole Economy section!!
We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.
Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.
The most uncomfortable seat i’ve ever had on a flight
If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.
For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.
did internet check in but still had to get checked in at the counter and this was not the first time. Bummer!
Paying $75 for my bag is disgusting. Got off ground late so I missed my connections. Kept us waiting for passengers in the cold. Will not use them again.
As always, Lufthansa checked my carry-on luggage, even though I was in front of the line. No other airline in the world does this. It's so annoying and unnecessary. There was enough space for it in the overhead bin. It's a TUMI Continental Carry-On. If you have the chance, rather fly easyJet or Condor on this route.
Someone sat in my seat and this made boarding protracted and unpleasant. The stewardesses kept saying, “it is important that everyone be seated — or we will be further delayed,” but for a long time they did not tell me where to sit. At the end of the flight a baby screamed loudly for several minutes and it took ninety minutes (!) to get through EU passport and customs. We had to stand the whole time in a an overheated room. The seat on the plane was narrow. These things are not all Lufthansa’s fault but they made for a somewhat unpleasant trip.
Everything about the flight was excellent except for the fact that we had to wait one hour on the tar app and then I had to race to catch my connecting flight with the next stop
The flight on time, flawless check in and boarding process, the crew was very friendly.
Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.
Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures
Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.
Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!
Knowing that there was weather in other areas of the world, united airlines should have planned better than it did. The flight was 5 hours late. United has no regard for its customers
Flight itself fine, big problem with KAYAK. Revised e-ticket sent in July stated departure LHR 10:55, arrival SFO 13:45. (a believable local arrival time given flight length and time difference). When we got to LHR there was no 10:55 flight to SFO and were advised that in fact flight LH2473 was arriving in MUNICH at 13:45pm, and that we would need to get a connecting flight arriving in SFO at 18:55 local time - over 5 hours later than expected. 1) you the booking agent made an error on the revised e-ticket you sent, omitting the Munich stopover and incorrect SFO arrival time. 2) I booked a DIRECT flight and 3) we had to cancel plans this end as a result, even though the team at LHR did a great job moving us to a later direct flight getting us in 2 hours earlier than the flight from munich would have.
The travel on premium economy class was very positive. Comfortable with plenty of space and leg room. The service throughout was top notch. Crew members were kind and helpful. Food and entertainment were excellent.
Long line with check in at the DIA British Airway counter.
It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.
Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience
There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.
We never made it onto this flight due to BA's lackluster organisation.
We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.
Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.
Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable
The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.
