Find Cheap Flights from North America to Colorado

Pros: I've learned to pack whatever I need into a backpack that's within their personal item limits. This makes traveling on cheap flights easy.

Pros: Everything was very timely. This was my first time flying on Frontier and some friends had warned me to expect delays. But everything went exactly as scheduled, which was great. Leg room was pretty decent, to my surprise.

Cons: The seats are somewhat uncomfortable and the tray tables are so small they are useless. No free drinks or anything at all. I at least got a cup of water on the flight out, but was offered nothing at all on the flight back. You get charged for EITHER carrying on or checking bags, which I knew beforehand, so I can't really complain about that...it's pretty ridiculous though. Everyone is going to bring a bag SOMEhow, so why not include one of them??

Cons: My suitcase was broken into things are missing and frontier operator didn't seem to care said I wasn't missing enough to warrant a claim

Cons: More delay notices and flight departure changes than I can count. Conflicting times in email notices versus the app versus text alerts. Customer service went straight to voicemail. I may have been able to drive across the country faster. Currently arriving in Denver. My connecting flight left yesterday.

Pros: The punctuality of the flights

Cons: Better inventory if drinks offered

Pros: Crew was polite

Cons: Not lose luggage, have a better system in place to deal with system downs. PICK UP YOUR PHONES AND RETURN MESSAGES

Pros: Nothing. But it's the cheapest flight, so I can't complain.

Cons: The seats are very uncomfortable. During the boarding, it was totally unclear what is the current zone. When I tried to board they said I should wait for my zone, but there wasn't any information on the screen so it's hard to know, especially if you listen to music and don't hear announcements. Please improve this!

Cons: If spirit would be like other airlines and offer even a drink without charging or something.

Pros: Quick smooth flight with professional service, would recommend.

Cons: It was impossible to find a dog carrier that was up to your standards. I ended up settling for something last minute. It would be nice if pet standards were more clearly identifiable.

Pros: Mediocrity is really the aim of an airline this tier, correct?

Cons: The hour delay, on top of an already 3-hour layover, in a terminal that wasn't even connected to the rest of the airport. The least you could do in a situation like this offer complimentary snacks to make up for it.

Cons: Flight Attendant skipped our row when offering drinks. No wifi, no entertainment, no snacks. Paid $25 to check one small bag.

Pros: Direct flight at a great price.

Pros: Actually, the entree was good!

Cons: As always with American, we take off late - today 25 minutes. Constant announcements disrupting sleep - another common feature. And please don't thank me for choosing American, it's the only option from Philadelphia for the locations I travel to. Recently I traveled twice to Newark (an extra hour away) to avoid having to fly American.

Pros: One of the crew members was rude on several occasions - the rest of the crew was fantastic.

Pros: The plane was new on the interior and comfortable.

Cons: My bags were not checked all the way to my destination, I had to get them re-tagged and checked for this part of the trip and the American Agent was EXTREMELY rude and made us pay oversized bagge fees even though our baggage was within the Qantas allowance, the main carrier for our flight.

Cons: The unfortunate delay prevented me from attending my grandmother’s wake. Fewer delays would be helpful.

Cons: Seats are terrible - need replacing-worn out; say like Queen Latina, setting on top of one another; absolutely no leg room!

Cons: Delta Comfort isn’t so comfortable. Seats are too skinny.

Cons: Late

Cons: Will never fly spirit again worst ever

Pros: It got my to where I needed to go....eventually

Cons: Didn’t like the hidden fees such a buying your seat. Good thing I checked my email the night before and saw that. Flight was delayed 4 times with no explanation. Won’t be booking again with Spirit simply over the hidden fees.

Pros: Good flight, on time, good crew.

Cons: The bag fees especially when making a change from checked to carry on are beyond excessive. $60 to carry on a bag? The nickel and dining is horrific.

Pros: Connecting flight

Cons: Seat size

Pros: Plane was clean, crew was very nice

Cons: The most uncomfortable seats I have ever sat in. No cushioning, No seat recline

Cons: My flight was diverted due to mechanical issues, we had to be bussed to my connecting city causing me to miss my connection. No offer of vouchers or food coupons. No more flights to my final destination, had to book thru another airline. This is absolutely unacceptable!

Pros: The crew on my flight from Minneapolis to Denevr was funny and warm and friendly and really amusing. I believe their names were Chris and Tate (I might have his name wrong) . Thank you, Tate, for being such a funny and entertaining person on what would otherwise have been a very boring flight. I hope he's on my next flight with Frontier.

Pros: Crew

Pros: Crew did giveaway game for miles, were overall very nice and polite. Lots of leg room

Cons: Seats aren't incredibly comfortable

Pros: Overall I liked the price. Never had any problems with Feontier before so that is why I booked it.

Cons: Leaving Denver it was confusing when boarding because the boarding agent was talking on the loud speaker and was saying that it was going to be a fast turnaround and some other stuff but more like rambling something about we were going to be late to Dallas. We wound up being right on time when we landed in Dallas. Wasn't really sure the purpose of the confusion.

Pros: The cost seemed to be good up front, but...

Cons: This airline is full of hidden fees. If you are traveling with someone and want seats next to each other, you have to pay an extra fee. Also, the airline only allows you to have a personal bag (a purse, laptop bag) for free, but they charge you for a carry-on. I had to pay $40 EACH WAY, so it ended up costing me $80 to travel with a carry-on. The return flight was delayed multiple times with no explanation as to why. Frontier was the only airline with delays, so it wasn't the weather. The seats on the plane do not recline, are not padded, and are overall not comfortable. I was overall disappointed with my experience with Frontier. It seemed like a good deal at first, but after paying all of the extra hidden fees and the delays, I would not recommend this airline.

Cons: Seats were extra and carry ons were extra. Not worth the price.

Pros: Boarding was fast and efficient. We left on time and arrived early.

Cons: You have to pay for carry-on and/or checked luggage and the space in seats in very cramped, particularly for legs.

Pros: Friendly attendants and an on time departure. Flying terminal 2 in Minneapolis is easy and much less crowded.

Cons: The food wasn't free, but that was expected.

Pros: Flight was better then expected.

Pros: From the beginning of my trip at DFW there was this very polite black assistant who help me get my ticket and a wheelchair all the way through my existing DIA.. The flight crew were also a lovely set of people...

Pros: The crew was amazing

Cons: N/A

Pros: Nothing.

Cons: It was the same thing. Almost got charged $100 to carry on one of bags which I had already carried on the other flight.

Cons: did not inform the extra charge for carryon.

Cons: Mechanical issue with the plane was reported the night before and not looked at until next morning after all passages had to be boarded. This caused all passengers to have to be unloaded and wait numerous hours before knowing if/when we were leaving. They passed out a handful of breakfast voucher then stopped until about an hour later they gave the rest of us our vouchers.

Cons: Seats are cramped and uncomfortable to the point of physical pain.
