Find cheap flights from Denver to Salt Lake City from $29

I love the free wifi and headrest screens. I would consider Delta even more because of this but the seats aren't so great. The snacks aren't very good in my opinion. I bought a Bloody Mary and that was great! So just be comfortable with better snacks and the airline world will be yours.

Temperature in the plane was quite warm for the entire flight - actually just outright hot making for an unoleay4 hours. Crew either couldn’t or wouldn’t do anything about it. No acknowledgement or apology. All passengers were commenting on how hot it was.

How about not delaying a red eye flight by 3 hours and causing a chain reaction of missed connecting flights

First class? Seriously? We got a wider seat and a little extra legroom. The plane didn’t even have TV’s. Not a huge deal, but there was nothing first class about this except the price tag.

Boarding started almost 20 minutes late with no explanation. Then the take off was delayed by 15 minutes with no update or explanation from the captain which was very stressful because I had a connecting flight with a very short layover. The The flight tracker on the screen at my seat was for a different flight and the QR code for the menu did not work. I asked for Sun Chips which were shown as harvest cheddar flavor on the website but the ones they gave me were salsa and I'm allergic to tomatoes and I couldn't eat them. The flight to Tulsa was okay but there was no Wi-Fi or entertainment on board which would have been nice to know

I love the food options, I don’t mind paying an extra $10-$12 for sandwiches, fruit, cheese, and crackers, and such. I’m glad they offer it!

On time departure and early arrival. Kind and professional service from flight crew

We were delayed 2 hours leaving STL. I had 20 mins from when we landed in SLC terminal A to make it to SLC terminal B. I had to actually run! thankfully I made my flight but 3/4 legs were delayed to some capacity.

Flight was OK from Detroit. The bag check process and TSA process at Detroit was absolutely appalling. Very confusing, totally up to passengers to print their own baggage tags, very long lines to get baggage checked after you print your own label, insufficient Delta personnel to handle the mass number of passengers, etc. Getting through TSA was difficult and confusing and eventually had to move down several flights of stairs to go through security at a recently opened location. Would rate the entire check-in process as poor as I have ever seen.

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Delayed for maintenance issue?? Should have been addressed before boarding. Put my bag on an earlier flight, but didn’t ask if I wanted to change to an earlier flight. Arrived to find my bag locked up and no agent to be found when I landed.

We learned certain countries (a few) require a notarized letter from an ex to give permission for children to travel to those countries with the other spouse together with birth certificates. To find this out one hour before flying—not good. Nowhere is it documented by the airlines though they require it. Make sure about all documentation required.

You could have been ON TIME! And I was miffed because I spent an extra $82 to get my seat and the steward put a woman from the back in my aisle for nothing because her movies wouldn’t work. I’ll try that next time and save $82!

Left Denver late, then sat on tarmac 30 min after arrival

Everything was good, 20/30 minutes late waiting on a crew member. It’s hard to keep employees. Or serious employees I know. I remember one flight from Houston of Frontiers was almost 18 hours late. And another 4 hours late very poor. But I would rather be late and safe than the on the news. Thank you.

Bought seats on the flight and they were supposed to be 2 and a jumpseat. Plane clearly changed and it was a regular 3 seat row. Asked for a refund and was denied. If I wanted to sit next to someone else I wouldn't have bought the seats..

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

It’s a cheap airline and I wish if they had better seats.

Seats are cramped and uncomfortable. You have to pay for everything and it is very expensive.

For a busy travel season, everything was clearly marked, correct, and smooth. My favorite travel description is “UNEVENTFUL,” and this trip met the mark!

The flight and crew were fine. When we (several groups) arrived in Norfolk on Sunday we discovered our bags had not arrived. The staff at norfolk airport was less than helpful. Told us our bags wouldn't arrive until Thursday. When asked what happened they said it bags never made it on the plane and it happened all the time. When asked about reimbursement for replacement items the desk agent said we could try to submit receipts online, but they weren't sure we would be reimbursed. I understand this is a low cost airline, but this was really beyond poor customer service.

Frontier is a no-frills airlines were the focus is low cost. You get basic service so don't set your expectations high. Watch out thought because this airline, like a few others, will try to nickel and dime you.

Flight had mayor delay. The onboarding took forever and was poorly conducted. AC was not in it was very warm in the plane.
