Find Cheap Flights from Colorado to Boston

Cons: Gate checked baggage took forever to be brought to the jetway. I’ve been on several UA flights. It seems to be a major problem with UA and their contractors. They don’t load bags quickly.

Cons: Did not seem to be able to control the movie, to restart, or FF or REWIND.

Pros: The crew was helpful and nice.

Cons: It was delayed a lot.

Pros: The crew was fine.

Cons: United is consistently late and unhelpful with addressing travel delays. The first leg of my flight was delayed which would have caused me to miss my connection. United staff could not have been less helpful. In the future, I will try to avoid flying United wherever possible.

Pros: We flew on a newer plane which lead for a comfortable flight. Acceleration was smooth, no jerk. Overall turbulence was minimal.

Cons: Flight was delayed. On time departure would have been ideal but thankfully the delay was minimal.

Pros: The crew was very good, the plane was clean. The seats seemed brand new and were relatively spacious.

Cons: I was not made aware that the regular seats do not recline as they do on all other airlines I have ever traveled on. Since I was taking a long, red eye flight it was impossible to sleep. When I asked an attendant I was told that they are 'predesigned for your comfort'...

Cons: Frontier has great prices, the bag thing is a pain, but you get what you pay for, l just work around it...

Pros: Nothing

Cons: Customer service

Pros: Comfortable seats and the video capability.

Cons: Delays but that's not on them.

Pros: Always a winner. We had regular seats, not extra legroom and they really are roomier than other airlines. Love the snacks and the little bottle of water that I can take with me after the flight. Love that wifi is free and available

Cons: nothing

Pros: Comfortable seats, snacks, good price, nice & helpful were all the flight attendants and persons at the counter. Flight was 20 min late arriving at Denver, but our pilot got us to Boston on time-much appreciated. Free WiFi was great.seats and the next plane (my plane)o not

Cons: Could have taken an earlier flight from Boston to DCA, but there was $75 change fee even though the plane had lots of seats. But I do not hold this against JetBlue.

Pros: The crew was awesome. Christina went above and beyond

Cons: Every flight by JetBlue out of Denver to Boston has had a problem. Been canceled and or delayed Everytime. This time was delayed 30 mins then another 30 mins then the delay was retracted via email but when I arrived to the airport the delay was still in effect. Ended up being delayed 20 mins but it was chaotic and frustrating with no apologies

Pros: I liked nothing about it. It was delayed. We sat on the tarmac for 30 min after we landed. I missed my connecting flight. my original time to get home was 3 pm it is now 11 pm only because American Airlines had a flight I could get on because spirit had nothing until the next day.

Cons: on time flight. a staff who looked like they didn't hate life. some time of in flight entertainment.

Pros: Nothing

Cons: On time, better service.

Pros: The seats surprisingly had more legroom than expected, the crew was very friendly, and the aircraft was exceptionally quiet. We also arrived almost 30 mins ahead of schedule.

Cons: Not much! This is an "a la carte" airline, so you purchase whatever you want and skip what you don't. It definitely isn't like flying on Emirates, but for what it is, Spirit does a very good job.

Pros: Great price ticket

Cons: Not crazy about buying a ticket then receiving an email to check in and pick seat then every seat on the plane has an up-charge if you select one. Or roll the dice and hope you you don't get a window/middle seat because the plane has the lowest amt of legroom on any American plane. I'm tall guy.

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

Cons: At least free water

Pros: On time boarding. Good entertainment options, friendly staff

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

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

Pros: The crew was friendly and helpful.

Cons: Better snacks would be nice, and there was no entertainment available, even for personal devices.

Cons: Transfer from international (T5) to T1 at O'Hare is very unpleasant..Generally O'Hare is a terrible airport.

Pros: Empty seat between me and another passenger helped a lot. Easier to travel.

Cons: Just too cramped and not enough leg room. Charging for a carry on when there was so much empty space in the luggage compartments. Make your money more kindly and not so much gouging.

Pros: Nothing

Cons: The seats don’t recline but should if you are doing a red eye. We landed an hour early but the speed caused non stop turbulence after being told it was going to be a smooth flight. landing a red eye an hour early is horrible for anyone that has pre-arranged pick up

Pros: Not much

Cons: was not happy about the prices of baggage that were not mentioned upon booking and the seats were very tight and not comfortable. No wi-fi, entertainment, think I will fly United in the future

Pros: The crew was nice. The pilot kept us informed - problem with paperwork so we could not depart and we were just sitting at the gate.

Cons: The plane was very late and then in addition there was a problem with the paperwork so we were further held up. Meant we got in at a bad time for rush hour in NY. A 3 hour flight ended up taking a whole day. I had already left for the airport by the time I got an alert that the flight was delayed.

Pros: The crew was awesome. Christina went above and beyond

Cons: Every flight by JetBlue out of Denver to Boston has had a problem. Been canceled and or delayed Everytime.

Cons: All was great

Pros: Cost and simplicity of a red-eye flight

Cons: Phone.chargers by the seats

Pros: Nothing. We didn’t make the connecting flight.

Cons: There could have been communication between flights. Had Spirit cleared a gate for our plane in a timely manner and contacted the connecting plane to wait 5 mins we could’ve gotten onboard. Absolute catastrophe. Will be leaving terrible reviews for customer service too.

Cons: On time departure and arrival

Pros: Empty flight- every passenger could have had their own row! Excellent piloting through a rough approach on a short landing.

Cons: The weather upon arrival- uncontrollable. So, nothing else about this flight could have been better.

Pros: Plane left on time and got in early. Flight crew unusually pleasant. Service fine.

Cons: I upgraded my seat and had hoped to get an aisle seat. When none of those were available, I chose a window seat. However, when I took my seat, I was sitting next to a wall, not a window. Bummer

Pros: Crew was night

Cons: Mechanical delay, then no air conditioning on our side if the plane, missed connection, terrible customer service

Cons: 2 hour delay because pilot missed connecting flight...also Stewart literally bumped me 6 times going back and forth without apologizing out trying to stop hitting me. Took a lot for me not to say anything as I know this is tight corridors, but I was unable to sleep on my flight due to the Stewart

Cons: My flight was extremely delayed for no apparent reason and it made me waste half a day sitting in the airport

Pros: I liked nothing about Frontier Airlines. Horrible service, cramped seating, unruly passengers and the flight time just kept getting delayed. I never want to fly with them again!

Pros: The crew was awesome and efficient. The flight was on time.

Cons: The seats were terrible. We had to pay for drinks. The baggage check area was closed until an hour and a half before the flight.

Pros: Comfortable seats. For cheap seats.

Pros: Great entertainment and service. Great leg room too.

Cons: Very uncomfortable seats, hard to sleep in.

Pros: No food served only soft drinks and chips

Pros: Leg room wa nice. XM radio is great

Cons: No issues.

Pros: Cost and simplicity of a red-eye flight

Cons: Phone.chargers by the seats

Pros: Crew was great. Seats were comfortable, but I was beside a tall man with not enough room for his legs in his area.

Cons: If parents could have controlled their 4 screaming toddlers and one of them kicking the tray table in front of her the whole trip.

Cons: Please offer free water.

Pros: Nothing. Had to pay for a bags that actually fit into the dimensions specified

Cons: Overall experience

Cons: Plane 2 1/2 hour delay

Pros: The inflight crew were great. The price of the tickets were also good.

Cons: The crew at the check in on our way out of nashville had the worst attitude I have ever experienced from an airline. They got us quickly up to the counter (good) but when I had to ask questions because I didn’t have time to read the signage they got an attitude with me. “Didn’t you see the sign?” And turning to another employee, “isn’t there a sign with all the information posted?” Same employee came down to the terminal and announced the wrong destination for our flight while we were boarding. On the way out of Miami and back to Nashville the crew had great attitudes but it was so disorganized we had the longest line to wait in to check in for both concourses. People were going to miss flights. They fixed that eventually but I’m not sure they did it fast enough for some. Getting through security was far faster than check in. Also, they nickel and dime you for luggage, snacks, etc. It’s a no frills flight. I’ll probably give them one more chance though.

Pros: Crew was polite and friendly

Cons: We left about 30 minutes late

Cons: The usual...leg room, seat spacing/size, lack of decent food options...

Pros: We landed 45 minutes early!

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.

Pros: Check in and departure very quick, efficient and professional.... very intuitive and helpful when observing that customer is in need

Cons: From a customer service standpoint, I Would lower or not charge business or first class rates on a jet in which the seats for the above mentioned clearly have no physical distinction from those in economy class. Just a thought.

Pros: Crew was great. Planes were on time.

Cons: Takeoff and first half of ORD-MCO leg was a little rough. Not the airlines fault though.

Pros: Nothing

Pros: The crew was amazing once we got to the gate! Line to check bags was very long and slow as there was only one clerk but within about 15 minutes, 2 more clerks showed up.

Cons: Seats were not comfortable. I was fine but my elderly Mother was pretty uncomfortable. That would be my only complaint!

Pros: I liked nothing about Frontier Airlines. Horrible service, cramped seating, unruly passengers and the flight time just kept getting delayed. I never want to fly with them again!

Cons: More space to breath. More comfortable seats.

Pros: Crew was friendly and helpful. Efficient in boarding and disembarking. On time and reliable gate assignments. Comfortable seats with ample leg room. Option to check bag at the gate made for more room for overhead items. Desirable options for snacks and drinks. Complementary TV/ WiFi.

Cons: Quality of TV/WiFi could be of higher quality. Can’t think of anything else.

Pros: The crew were very nice and respectable and did their job as professionals! We landed on time and the disembarkation was smooth, with no problems!

Cons: The person on my right (I was in the middle), wasn't very considerate! He hogged both arm rest, had one of his feet on a personal bag (I had in front of me) and was just plan rude and impolite as a passenger!

Cons: The specific plane we had for the short trip had mediocre TVs and the seat's headrests were too short for me to comfortably put my head back.

Pros: Boarding seemed to be pretty efficient, especially compared to my most recent experiences on American. Flight was smooth (of course, airline doesn't have much to do with that). Got to my destination along with my luggage. Did not feel cramped on the plane and I was in a regular seat. Did not feel like I had to spend through the nose to just have a passable experience.

Cons: Flight was almost 2 hours delayed. Plane felt a little shabby. Sometimes I found it hard to understand the flight attendant who did most of the announcements - she had an accent, which would have been fine, except that she either spoke too fast, or was mumbling. All that together, made it hard to understand her. Pilots never spoke to us. Not once.

Pros: It got us here

Cons: Flights were delayed

Pros: Very poor airline and all related services were very low standard

Cons: I suggest don’t travel on this cheap airline.

Pros: The seats surprisingly had more legroom than expected, the crew was very friendly, and the aircraft was exceptionally quiet. We also arrived almost 30 mins ahead of schedule.

Cons: Not much! This is an "a la carte" airline, so you purchase whatever you want and skip what you don't. It definitely isn't like flying on Emirates, but for what it is, Spirit does a very good job.

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

Cons: Roomier Seats

Pros: That I got home.

Cons: See above.

Pros: Like the customer services and the snacks and soft drinks.

Cons: Nothing

Pros: Plane left on time and got in early. Flight crew unusually pleasant. Service fine.

Cons: I upgraded my seat and had hoped to get an aisle seat. When none of those were available, I chose a window seat. However, when I took my seat, I was sitting next to a wall, not a window. Bummer
