FAQs - booking Utah flights

  • What can I expect from Lufthansa when flying alone with a child?

You will be allowed to place their pram in the hold for free and distilled water is available for food preparation. You can get free nappies should you run out. Try to fly at night so your baby will sleep throughout as much of the flight as possible, and book a free bassinet for a peaceful sleep.

    If you book flights for children between 5 and 11 years of age with Swiss Air, they’ll be allowed to fly alone if booked with an Unaccompanied Minor ticket.

Top tips for finding cheap flights to Utah

  • When booking flights from London to Utah you may want to fly from large, more established airports such as Heathrow (LHR). If you are leaving from London city centre it would make sense to fly from the smaller, but highly-professional London City Airport (LCY). You will be able to reach the airport far easier and clear Security much faster, leaving you more time to relax before your long-haul flight to Utah.
  • When taking public transportation to London City Airport the tube will be your easiest and most economical solution. The DLR tube line runs from the city to the station at the airport. Taxis and Ubers are available with a road travel time of about 20 minutes.
  • If you have any special dietary requirements when you fly on KLM Airlines you can request a special meal beforehand. The airline gives every passenger a bottle of water, a warm meal, salad and dessert and there are also snacks served on long flights. You are welcome to get extra drinks and snacks for free at any stage. Vegetarians are well catered for on KLM.
  • When you arrive in Utah you may make use of the capital’s main airport, Salt Lake City International (SLC). This large airport is very accessible for passengers needing mobility assistance. Attendants can assist with wheelchairs throughout the airport at any stage. You can also find restrooms that are accessible, as well as restaurants and shops. If you do not have a wheelchair the airport will gladly supply you with one.
  • If you have flown with a pet from London to Utah they will be in need of relief when you collect them. There are animal relief stations at the Salt Lake City Airport just outside the airport and another 2 within security. This way your animal can do their business before you get collected or hop onto public transport.

London to Atlanta was good. Atlanta to Phoenix was not. Poor boarding as I had to check my rollerboard even though there was plenty of room in the bins. Crew seemed inexperienced. Sat just off the gate for nearly 30 minutes with no explanation from the pilot while the cabin got hot. I typically have a much better experience with Delta.

London to Atlanta was good. Atlanta to Phoenix was not. Poor boarding as I had to check my rollerboard even though there was plenty of room in the bins. Crew seemed inexperienced. Sat just off the gate for nearly 30 minutes with no explanation from the pilot while the cabin got hot. I typically have a much better experience with Delta.

Wonderful crew, great movie selection and good food. I prefer Airbus to Boeing, much more comfortable

I wish the inflight entertainment system options were broader, but overall this was a fantastic crew and I can’t express how cheerful, welcoming, and attentive they were.

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

I paid for a business class ticket on Delta. It was sourced to Virgin Atlantic. They changed out the aircraft which had fewer upper class tickets. Even though I'd checked into the lounge, was receiving alerts via kayak about the delay and changes; no one informed me that the seat would be changed - until I attempted to board and was told that I would have an economy seat or they could search to put me on another airline. Even the flight crew were informed of this change (10 passengers were bumped out of Upper Class) around 2 pm (1400) time. Hours would have helped to consider alternatives instead of making a last minute change. There needs to be compensation from both Delta and Virgin given this change in service/experience.

Movie selection was meh. Food was great. Crew as always great. I paid for premium because that’s the only way not to feel like a sardine. That’s how economy should be imo. Sadly passengers have to pay an extra $1000 to get what they should at base price but that’s all airlines. The airline industry in general treats passengers as cargo.

Ongoing flight was delayed. Staff at bag recheck was able to get us on an earlier flight. With only 20 minutes till take off we feared our bags would not make the new earlier flight. We were most delighted that they did and were there when we landed. Delta came through

When checking our bags at the Virgin Atlantic counter, the employee told us that we should go to Delta because we needed to verify our passports and our names. Fortunately the employee organizing the line stopped us and asked why we didn't hand over our suitcases. He sent us to another line and told the employee that we already have the passports verified in the reservation. She understood and received our suitcases. In London they have a general waiting room, where you stay until the gate number of your flight is announced. KAYAK informed us the gate number hours before the airlines did. Just like the flight to London, the legroom is too small. abusive for a flight of so many hours.

Bathroom broke, had to rush to board because of late exit of previous flight

Space and comfort was good. Staff could have been more helpful and friendly.

Plane features were VERY old and outdated. footrest cushion was completely lose, plane felt dirty and a bit grimy. i was in business class. the lead flight attendant, Mary made a few announcements that didn't seem to put the cabin at ease (it didn't necessarily bother me, but could have bothered others). she said "the seat cushions aren't FDA approved, so you have to put them on after we take flight." everyone had already applied the seat cushions, and saying something isn't approved for flight may cause alarm. she also said at one point over the announcement ... "we can't get up because we are too afraid of the jet stream impacts" -- again, not helpful to those who are nervous fliers.

Extremely comfortable airplane, everything looked brand new, how lovely! My seat in Premium Economy was ever so comfortable, I did not suffer the usual backache I suffer when doing the transatlantic flight. It felt like seating in a reclining armchair. I loved the foot rest, did not need to use the portable device I usually carry along with me to replace one. I loved the spaciousness in front of me, and that there were only two seats (Instead of 3 in coach) in the window row, wow what a difference in comfort. Coach seats are always just a little narrow for my hips. The support of the cushions was great, firm and offered good support . It was easy to come out of my aisle seat, although I'm 70. The staff was courteous, both meals were delicious, very carefully prepared, and creative (fruit + cheese for the second meal, instead of the usual bread sandwich)

The plane was up-to-date, and the free wi-fi was very much appreciated! All of the ports functioned well, and the entertainment choices made the flight much more enjoyable. One of the flight attendants was unfriendly, but the flight was enjoyable overall.

3 hour delay before takeoff & another 30 minutes on the plane before taxi to runway

Rudest flight attendants ever, waited over 20 for light to be answered and it never was then tried to flag down an attendant who said someone else would come, just needed water to take some medicine Food bad

My entertainment unit kept locking up and had to be restarted multiple times. Also those commercials for Budapest and Ralph Laureen. Come on those were stuff only those who can afford the outrageous fees of first and business class would be interested in.. And the fact you have no military discount is not good either,

I was a Wheelchair Assist’ passenger on a London Heathrow to PHL flight yesterday. The process of getting me and my carry-on bag from the ticket counter to the gate was not good at all. It was the worst in my 5 years of experience using this service offered by American. The Philadelphia ‘Wheelchair Assist’ service was, and always has been Excellent! Not so at Heathrow. I was handed off to three different wheelchair drivers; had to sit in a very dingy holding area for 30 minutes while waiting for our gate change announcement; got crammed into a overloaded service vehicle to take me from the holding area to the gate ; was dumped at the end of the line of already-boarding passengers with my heavy carryon and no one helped me up the ramp way at the gate to board the plane. Overall it was a miserable experience!

Crew was nice, aircraft dated, entertainment same. Internet is expensive and terribly slow. Food pretty bad

Horrible experience. Food was ridiculous, insufficient, and not appetizing at all. They served sugary granola bar for breakfast. Furthermore, my bags were delayed and delivered damaged and American made it impossible to file for damages. Furthermore, the flights were delayed causing unnecessary stress given the connecting flights. It was awful experience, would never want to fly American.

My table was broken so it made it difficult to eat the food during the service. I was also informed that my luggage did not make it with me to Phoenix. I live two hours away so this makes it even more stressful to try and arrange a time for pick up

Flight was delayed. But my finances flight with JetBlue a week before same route was extra delayed and then cancelled at 2am when his flight was suppose to take off at 7pm was never provided a hotel or anything. Came back to airport and his rescheduled flight was cancelled again for 2 days later. Was told since it was a weather issue they don’t do refunds. But that’s a lie because I booked him on another airline at the same time and they were able to take off perfectly fine

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The seats were roomier than other airplanes I’ve been on.

Jetblue provided a very good service during the flight, the plane in a very good condition, the crew is professional, everything was on time. That's it!

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The new seats JetBlue uses angle downwards, so the entire flight you are sliding forward out of your own seat. These seats suck!

We liked the flight, but not in JFK, not in Gatwick it is no lounge and this was surprising and disappointing. I think by now it is understandable that COVID will not go away and why it should not be business lounge?
