Find Cheap Flights from Oregon to Denver

Pros: Cheap flight, quick boarding.

Cons: Cramped accommodation, extra fees for luggage, no complimentary beverage service. I’d call it the Grey Hound of the air, except I recently took a Grey Hound and I was much more comfortable.

Pros: Boarding was ok, flight time was 2.5hrs, getting off the plane was usually slow - but as always, it's great to get off!

Cons: Nickle and dimed for any and everything. Seats are truly terrible - needed a chiropractor to fix the damages! Luggage policy is a joke. Used to be my favorite domestic - Frontier has really moved up to the top of the bottom of my list.

Pros: Pdx is a great airport

Cons: Getting charged for EVERYTHING with frontier. Pretty classless company.

Pros: Not much!!

Cons: Extra bag fees that Frontier charges are as close to legalized robbery that I have ever experienced.

Pros: WIFI allowed access to imessage

Cons: "Free" movies and TV didn't work

Pros: We landed 45 minutes early!

Pros: Crew was great. Food was ok. Seats were nice

Cons: It was good. I’m satisfied

Pros: Flight was great

Pros: Delta in flight entertainment is great.

Cons: Always delayed.

Pros: Crew was amazing and super helpful.

Cons: Just the fumes of fuel inside the cabin was nauseating. Never had similar issue with air travel before.

Pros: Boarding was fast

Cons: The seats were incredibly uncomfortable. This was a Comfort + seat. Very hard, unbearable for an overnight flight.

Pros: Flight was very late- about 45 minutes because of some problem with the "paperwork" they said. It was a beautiful day and the crew was ready to go, but we all sat for a long time before being allowed to leave Madison. It's especially bad when we've all made ourselves arrive at 5am for a 6am flight

Cons: on time departure

Pros: Price

Pros: nothing

Cons: being on time so I could have been on the flight

Cons: Please offer free water.

Pros: The crew was super nice! The plane was on time and the flight was uneventful -- a good thing when it comes to flying!

Cons: It was really all good!

Pros: Very pleasant crew.

Cons: Very late in departure from Victoria. Long long delay in receiving oversize baggage. Incorrect directions by airport employees in Seattle, resulting in wrong floor, rescreening. But very helpful Alaska enployees to assist in unscrambling.

Pros: Crew was great, seat was ok

Cons: Everything was groovy

Cons: Seat assignments. Friendlier boarding. On time operation.

Cons: The flight to San Diego was late. The flight back to SFO was also late. Never flying Alaska Airlines again

Cons: Two hour delayed.

Pros: On time with easy boarding and very helpful staff.

Pros: Entertainment options were great

Cons: Crew (one member in particular) was rather short and rude to passengers who may have been unaware about the device holders on the back of seats. These are new for some. Use it as a teachable moment.

Pros: The flight crew were very good.

Cons: We arrived late in Dallas, due to weather. Our flight to LA had already locked the door, the lady working the desk when we got there, said we had missed the flight and walked off. Two more ladies came to the counter, but would not help us, finally a fourth lady came and helped us.

Pros: Frontier has introduced a new concept in ergonomic torture - the 2-inch clamshell passenger seat, made of hardshell plastic. At least on our first flight we got the grudging 3-ounce diet coke watered down with ice. On this flight though, they didn't serve anything, not even water. Of course you pay for luggage. And Frontier charges you even MORE for a carry-on. I plan to avoid Frontier at every possible future opportunity.

Pros: Got home safely

Cons: Both ways were delayed with no explanations

Pros: Not one thing

Cons: My number one issue was the staff. Totally unhelpful and unaware of guests needs. You should not advertise frontier economy tickets to people over 6 feet tall and/or wider than a 14 year old.

Pros: Quick boarding. Early departure was nice.

Cons: Seats are basically hard plastic and even a short 2 hour flight hurts. Bus seats are more comfortable nowadays. Tray table was smaller than my tablet. Why so small? Why has flying become more like being a sardine than some awesome way to get places faster? Greed. Plain and simple. Is not about the customer experience, it's about how much money can the airlines wring out of each customer. Wish we could go back to when it was an experience to enjoy rather than endure.

Cons: Crew was late. Delayed the flight by 45 minutes.

Pros: Friendly flight attendants

Cons: Forced by gate agents to put a tiny (5 inch) shoulder bag (like a tiny man-purse) into my carry-on. United blamed this dumb harassment on TSA. Huh? Super petty & annoying - the bag was tiny!!

Cons: Not a broken chair, brighter display screen

Pros: Pilot was communicative, and seemed as frustrated as us

Cons: On the ground crew couldn't handle getting the plane into the gate. We were directed to three different options, leading to at least an hour delay once on the ground and difficult connections.

Cons: I showed up an hour before my flight with no luggage to check or carry on. The line to TSA was almost nonexistent and the gate was close. The auto check in told me to go to frontiers desk to check in. No one was at any of the frontier check in counters event though every other airline had at least one person at theirs. There was a sign that said I was too late to redeem my ticket due to a 45 minute rule that wasn't mentioned anywhere in my flight itinerary or multiple emails from kayak and frontier. No one at the airport could help me without a frontier representative, they didn't answer my call to their 800 number and I missed my best friend's fathers funeral.

Pros: flight attendants were great!

Cons: seats don't recline, very uncomfortable. tray tables are minuscule. charged for everything (sodas = $2.99, snacks also $2.99, extra for carry-on bag).

Pros: Flights went fine.

Cons: I will never choose to fly Frontier again. This was my first and last time. There is a fee for everything which makes the cost of flying with them significantly higher than quoted. I couldn't believe that you have to use a credit card to get a bottle of water or a small snack. If you don't check their website you can pay double to check in bags when you arrive. Not at all consumer friendly.

Pros: Quick boarding. Early departure was nice.

Cons: Seats are basically hard plastic and even a short 2 hour flight hurts. Bus seats are more comfortable nowadays. Tray table was smaller than my tablet. Why so small? Why has flying become more like being a sardine than some awesome way to get places faster? Greed. Plain and simple. Is not about the customer experience, it's about how much money can the airlines wring out of each customer. Wish we could go back to when it was an experience to enjoy rather than endure.

Cons: Totally false information provided by Kayak re: seating and seat assignment. Sold as Austrian Airlines flight w/ links to their baggage policies and ability to pick seat. Arrived at airport and told I must check in with United, who charged me baggage fees contrary to Austrian policy.

Pros: Personable crew.

Cons: Middle seat

Cons: Landed 15 minutes early, waited for the gate open , then ended up 10 minutes late in a different gate further away from my next gate that we had a short connect time to . It's obvious that United spends all its money on frequent fliers so the rest of us are left to fend for ourselves .

Cons: Very turbulent day.

Cons: Duration

Pros: The flight was on time at departure and 30 minutes on arrival.

Cons: Since I got a good deal on the ticket, my boarding zone was “Basic”. That kind of sucked, but I still could fit bag in the airplane so it all worked out

Pros: Delta’s crew is always the best. On schedule

Cons: This was a 2 hour flight, some entertainment would be nice...

Pros: The seat get’s bit hard after 14 hours.

Cons: The food was ok but not great

Cons: Terribly long bag drop line. Also very slow to get bags at baggage claim. Overall mediocre flight. Will never fly them for any flights longer than 2 hours. A lot of nickel and diming with these folks.

Cons: Considering you paid for luggage, no complimentary beverage service and attendants whom expected "team" work to clean the plane, this was the worst example of customer service I have experienced. I travel frequently and very disappointed in Frontier's service and comfort. The space between seats were uncomfortable for a couple of half marathoners. Again quite disappointed and will be avoiding Frontier in the future, no matter the perceived savings.

Pros: Boarding went quickly.

Cons: The online check wasn’t working so I went to the desk. Which was fine, but the desk clerk was VERY rude. Not just to me but other passengers as well.

Pros: Didn't like a single thing.

Cons: Your horrible gate lady in Denver made us miss a flight because she decided to charge us $90 for 2 Carry on bags

Pros: The cabin attendant gave me a extra coke.

Cons: Connection times were too close. My seat was double book on the flight.

Pros: The plane was not full so I had room to spread out even in economy

Cons: Instead of breakfast being served upon arrival (at 8:30PM), a lite lunch might have been better. The meals seemed out of sync with the times.

Cons: Totally false information provided by Kayak re: seating and seat assignment. Sold as Austrian Airlines flight w/ links to their baggage policies and ability to pick seat. Arrived at airport and told I must check in with United, who charged me baggage fees contrary to Austrian policy.

Cons: Paying $25 to check a bag each way just to be able to do early check in on the app. I only had a carry on. Total scam. Shady AF. Also the United entertainment in the app does not work with Bluetooth headphones on an iPhone.

Pros: The care and good food was much appreciated. There were plenty of excellent movies to watch to make the time pass in an enjoyable way.

Pros: Snacks and drinks and movies on point.

Cons: No cheese its.

Pros: Seats were narrow and we were shoulder to shoulder. Plane was clean and all was on tkmr

Cons: Roomier cabin

Pros: Crew was good. It was great to be able to watch a movie, TV, or play a game to pass the time.

Cons: More let room when someone puts back their seat.

Pros: The seats are comfortable.

Cons: At the very least you can offer free water. After paying so much for a flight, I do not appreciate being charged $3 for water. A little customer service goes a long way. I am not too sure I will fly with spirit again. It’s the principle of matter. It was a huge turn off.

Pros: Nothing, was horrible

Cons: Better service

Pros: never happened missed it because spirit was delayed.

Cons: being on time.

Pros: I wasn’t expecting much from a “discount” airline but was pleasantly surprised by the crew and over all experience

Cons: Seat assignments. Friendlier boarding. On time operation.

Pros: Helpful polite people , on time, luggage was delivered quickly

Pros: Nothing

Cons: Speed and care

Pros: Crew was great.

Cons: Took forever to reach our gate and once we did, it took extra long for everyone to get off the plane. Ended up 45 minutes late for arrival.

Pros: Nothing at all had to cancel the flight and get a refund

Cons: If I actually got on the plane and get to my destination

Pros: Nice plane.

Cons: Bag fees, long and painfully slow check in line. No wifi on plane.

Cons: This was an absolutely terrible experience. I will not be flying frontier again.

Pros: Although I only got a water, other people were ordering, but the older flight attendant was not at all personable and was very impolite. Being a chef, I would never give poor quality customer service as he did. My flight attendants from DEN to TYS was much more personable and made the flight much more enjoyable.

Pros: united is united

Cons: Flight came in super late and missed the layover.

Cons: Some of the a/c power outlets did not work

Pros: I liked the touch screen displays in each headrest. Seats and leg room comfortable

Cons: Boarding was somewhat unorganized

Cons: Ran out of hot water on flight

Pros: The crew did their job. Some attendants were very kind, helpful.

Cons: Food could be better. Old aircraft, old style seats. Other airlines have improved this very, very much. Delta is lagging behind.

Pros: Flight attendants were very friendly.
