Find Cheap Flights from Portland to Denver

Pros: The crew was very nice and friendly! Very professional as well.

Cons: Snack choices were not that great. Something like cheese and crackers maybe?

Pros: Price

Cons: Clean environment. Comfort seats

Pros: The crew was nice

Cons: Allowing me to bring a carry on

Pros: I will never fly Spirit again.

Cons: I missed my connection because Spirit was an hour delayed on my first flight. I had to wait until the next day to get a connecting flight and Spirit didn’t even cover the hotel. I’ve never had an airline be less helpful (and I fly at least once a month). The small cost savings is NOT worth it.

Cons: The first leg of my trip home started by us being delayed by 30 minutes. Concerning because of connecting flight in Denver. Seats were too crowded-no leg room. I was forced to pay 45.00 to check a carry on bag because of liquids-The flight out on Alaska Airlines allowed for a checked bag at 25.00.

Pros: Nothing at all

Cons: Thought I would take a gamble and fly this Airline again. Flew them to Denver almost 6 years ago and was impressed. On May 3rd I flew them to Denver from Portland. Might have been the Worest fight ever taken. Flight was delayed almost 4hours when all said and done. The seats felt like something out of Disneyland ride, and my table was the smallest thing i have ever seen. Surprised I wasn't charaged a fee to have air on the plane. On positive I can say was the airline bought me dinner after being stuck for 4hours. Beware...

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.

Cons: Fees, cramped space, cleanliness

Pros: Friendly, comfortable service

Pros: The flight from the Denver leg to Des Moines was great. The crew was exceptionally friendly, especially the stewardess. I really loved taking the smaller plane into Des Moines. It made the boarding and deboarding go very quickly. In the future when traveling to destinations outside of a major hub, I will look for flights with smaller planes. It was an incredibly pleasant flight experience.

Cons: Flight attendant was not helpful with large package

Pros: Ronald fight attendant made our first time to Europe trip very pleasing. He was amazing.

Cons: nothing everything was perfect.

Pros: Hanging out in a cold airport all day for no reason

Cons: See above

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.

Cons: This was supposed to be a round trip, coast to coast, involving two flights each way. The first 2 flights were delayed, the 3rd was cancelled after several hours of delay, there were inordinate numbers of gate changes--5 for one flight, 3 for another. I was supposed to go on a 4th flight, but at that point, I walked over to American Airlines and bought a ticket home on the spot: No delays, no gate changes, no excuses, no weirdness.

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: It was fine.

Pros: The flight from the Denver leg to Des Moines was great. The crew was exceptionally friendly, especially the stewardess. I really loved taking the smaller plane into Des Moines.

It was an incredibly pleasant flight experience.

Cons: Being packed into the seats like sardines, not nearly enough leg room and even when reclined the chair sits too up right. When the seat in front of me leans back, I can't even lay my head down on the tray table because the space is too small for me to bend forward. So I'm forced to sit up right on two long flights, the first didn't even have in-flight entertainment. I can't imagine someone bigger than me (5'4" 150 lbs) being able to even reach the floor if something was dropped.

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: Misrepresented the price. All baggage costs extra.

Cons: Seats are very uncomfortable, no padding and the don't recline, flight attendants didn't seem to like their jobs...

Pros: Shitty cut rate airline. Never again. Kayak or Frontier.

Cons: They kept pitching their credit card. They charge extra for every little thing (carry ons, drinks), why would I want their card?

Pros: Crew was good seat comfortable

Cons: Better snacks

Pros: Landed early

Cons: There were not head flaps on the seat. The person seated next to me overflowed into my seat making it uncomfortably warm even with the air vent fully open. Was in & out of sleep during a red eye flight.

Cons: It was canceled

Pros: Amazing crew as always

Cons: Wifi on smaller hoppers

Cons: Didn’t enjoy the flight at all. Seats were uncomfortable, staff looked somewhat unkept and were gossiping loudly in the back during the flight. Snacks were not provided, only one drink for the entire flight. I will not be using Sun Country again.

Cons: We were unable to check in with SunCountry .. very frustrating!

Cons: Delays were not going explained

Cons: Great so far! Thnks

Pros: Very professional but friendly flight attendants. Best I’ve encountered in a long time.

Cons: Was very crowded, trays so tiny. No leg room. Checked bag price unreasonable. Cabin hot

Pros: Not much!!

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

Pros: Nothing

Cons: They change my flights

Cons: The fact I had to pay an extra 45 dollars for my luggage so all in all this trip was not convenient nor cheap.

Pros: Crew was pleasant and kind

Cons: Sitting next to the back bathroom, getting bumped by other travelers and the food carts, and the turbulence.

Cons: Late crew. Slow to depart added to delay. Arrival blocked by equipment in the gate, so we waited to get access to the terminal. 20 min after gate arrival, still no bags. Then one truck of luggage on the announced carousel and then...nothing. Secretly, the remaining bags were appearing on a differen

Pros: Good service, nice plane interior, Everything on time. Only problem was that the seats were uncomfortable!

Cons: United's hidden fees

Pros: The service, on time, employees very nice.

Pros: The ability to charge my cell phone via USB ports. Also the movies on long flights is really nice

Cons: Quicker way to get off plane

Cons: Wifi didn't work

Pros: Landed early

Cons: There were not head flaps on the seat. The person seated next to me overflowed into my seat making it uncomfortably warm even with the air vent fully open. Was in & out of sleep during a red eye flight.

Pros: Everything

Cons: It was perfect

Pros: Excelent job

Cons: I recomended to my friends

Cons: Seats and the seating arrangements were poor. Seats were assigned at different places even if you are part of the same family/ticket. The aircraft do not have 3-4-3 seat arrangements. So it would be difficult for families with 2 kids.

Cons: The plane was absolutely filthy and smelled of urine and and heavily spiced food. The seat assigned to me had liquid in it and I asked the attendant if i could have something to wipe it up and she just reseated me. Just filthy!!!! It was so gross

Pros: Pdx is a great airport

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

Pros: The crew was nice

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.

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: The seating was very good. We "accidentally" were issued seats in bulkhead which gave us plenty of unexpected leg room. Thank you!

Pros: Everything went well, from boarding quickly to landing ahead of schedule.

Cons: A mother with 2 fussy babies somehow sat next to me and they were extremely bothersome. Nothing was done to accommodate the crying babies, and we all know how annoying that is.

Cons: Be on time!!

Pros: The cabin attendant gave me a extra coke.

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

Pros: Crew was good seat comfortable

Cons: Better snacks

Pros: Despite boarding late, and sitting on the tarmac for half an hour since we missed our take off time, and having to move passengers around to balance the weight on the plane, we made it home alive.

Cons: We landed over half an hour late. Flight attendants needed to move passengers to balance the weight on the small plane, and asked for "volunteers." When there were none, the FA stood in the aisle and said we just weren't going to take off if nobody volunteered. They should have just MOVED people.

Pros: The crew and the boarding were good

Cons: No food. Just unhealthy snacks

Cons: It was all good ✈️
