Find Cheap Flights from Denver to Pennsylvania

Pros: Nothing.

Cons: First, an exterior light was broken so we were delayed so much that American recommended we reschedule our connection but we got to LGA and our original flight was still at the gate but they’d oversold it so we couldn’t get back on. And then, getting on connecting flight, the door broke so we were

Pros: Was not long enough

Pros: Not much!

Cons: Flight was 90 minutes late leaving Manchester so J missed my connection in Philadelphia! After a rebooking I was put on a flight to LA but that flight was also late and delayed getting to the gate in LA so I missed the flight to Seattle

Cons: Wifi didn’t work.

Cons: We are still waiting at the airport. It's been a 3 hour delay. Southwest just left to PHL. My first time flying frontier. Not a good experience.

Pros: I got where I needed to be at a low cost.

Cons: Crew seemed unhappy. Seats are even more compact than other airlines(or so it felt).

Pros: Friendliness of crew. Captains' explanation (on the return leg of our flight) of why it took sooo long to know why our flight was repeatedly delayed. Extra leg room seats for purchase.

Cons: Having to purchase my seat, paying to have a carry on and for EVERYTHING else- a la carte style!

Pros: The only thing I enjoyed was that the experience ended. Everything that was Frontier was horrible. My worst flying experience ever.

Cons: I didn't like; the 7 hour delayed flight, customer service, no manager, extensively long kiosk line, inaccurate updates from Frontier, and the unreclineable seats that I paid an extra $50 for

Cons: Left A bag behind in NY

Cons: It was canceled

Cons: Connection at Schiphol often tricky;

Cons: Food really bad on both segments.

Pros: Liked the fare

Cons: Crew not very welcoming—when boarding, no greeting, no eye contact; after being seated, crew member tersely asked to see my ticket...no please, no explanation, no thank you. In cabin crew did not make us feel safe , secure, cared for. This is the first negative comment I’ve ever posted.

Pros: was really helpful

Cons: need some pastel

Pros: Crew did a great job

Cons: Delayed flight with no announcement about a gate change.

Cons: Terrible delays. Charged me $400 for canceling the flight although it’s their mistake for delays. Then i booked Sun Country flight and didn’t make it. They harmed me $200 and gave me vouchers. Spent $1600 in one day to make it to my destination. Horrible experience.

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: I waited in line for nearly an hour to check in. There was close to 70 people waiting to be checked with only 3 agents working the check-in desk. This delay caused myself and several others to miss out flight.

Pros: Good legroom, they waited for the late passengers(it wasn’t just me!)

Cons: Free bev

Pros: Nothing

Cons: Not be delayed for 4 hours. Spirit should compensate me. I left work early only to spend my entire evening at O’Hare as they changed the departure time 6 times because of a mechanical problem with the plane

Pros: Crew was nice and decent on board experience

Cons: 5 hour delay messed up entire travel plans. Missed my connection have to sleep at airport.

Pros: good snacks and this route (DCA-BOS) has the 2x2 seat configuration so no middle seats.

Cons: I took this flight last week and this week and both weeks the flight were delayed a minimum of 1.5 hours

Pros: it was fine, unremarkable in all ways.

Pros: Crew was great. Movie selection was great!

Cons: Boarding organization.

Pros: Extremely smooth flight. Staff were very attentive.

Cons: Meal was average. Seats did not recline enough to facilitate sleep.

Pros: Crew was nice. Enjoyed watching one stewardess train another. Very smooth landing in Redding.

Cons: Flight delayed for about 20-30 minutes with personnel entering and exiting aircraft with no explanation for passengers after pilot had announced we would be leaving “on time.”

Cons: Delays

Pros: Movie selection was excellent. Bombardier jet was a notch above what I expected.

Cons: We were over an hour delayed on the first flight. The seats were super uncomfortable for the overnight flight. They left open seats in the upgrade section on the second flight - why would you ever do that?!?

Pros: Everyone was polite during the check in and boarding process and both occurred smoothly and efficiently.

Cons: Turbulence can be expected during any flight, however, when the entire length of the flight has turbulence and the pilots do not mention the possibility of this it can become anxiety inducing. It is most reassuring prior to take off knowing that there will be expected turbulence due to weather, and then continued updates during the flight. I believe communication from the pilots should be more than "prepare for take off" and "prepare for landing".

Pros: Boarding was quick and efficient. Crew was very nice.

Cons: Seats were extremely uncomfortable and didn't allow for sleep. Also extra fees for carry on luggage and food and drink are not necessary these should be free

Pros: It was very quick boarding and the staff was right there instructing you which was very helpful to me due to my age. (69) Same answer I gave while flying to the west coast.

Cons: Nothing was offered or given to add comfort to the flight such as a small pillow or blanket.

Cons: We are still waiting at the airport. It's been a 3 hour delay. Southwest just left to PHL. My first time flying frontier. Not a good experience.

Cons: The communication on the actual flight could have been better. The flight from Houston to Charlotte was not very informative as in weather conditions, traffic, or the time in which we landed was not gone over.

Pros: My departing flight crew was very accommodating for my baby and I. They were very pleasant.

Cons: I wasn't able to board first with my baby, so I had to try and walk through all the passengers with a baby, diaper bag and small carry on. It was a little difficult.

Pros: Had the fortune to sit with a passenger that had a service dog

Cons: Takeoff was delayed Two hours and 17 minutes with NO explanation.

Cons: The chairs

Cons: I wasn’t able to use the WiFi in my flight. It worked last time but was not even available on this flight it seemed.

Pros: Very attentive and professional crew.

Cons: The cabin was EXTREMELY cold!

Pros: Beats driving anyday! Fun crew!

Cons: A snack and drink would have been nice!

Pros: They are always great to fly... friendly flight attendants, great snacks, respectful of your time and are always uplifting (no pun intended!)

Cons: Nothing!

Pros: I am claustrophobic and prefer an end seat. My discomfort even prevented me from ordering drinks and food.

Pros: it's Frontier...just basic.

Cons: Charge for every possible essential after advertising low fares. Really uncomfortable seats, no recline, no head or neck rest. No wifi or entertainment on long haul flights.

Pros: Nothing e

Cons: Everything

Pros: Getting the flights was easy, used kayak. Tickets ultimately were purchased through priceline.

Cons: Flight was a round trip flight and American Airlines (or American Eagle, which is it?) changed my flights and I went from an hour layover and arriving at the time I desired to instead a three and a half hour layover and arriving after midnight.

Pros: Crew was nice.

Cons: Plane was very old (from the 90s?), cabin kept freezing all night. Now my husband's luggage has been lost and we are getting conflicting information on how to retrieve it.

Cons: The chairs

Pros: Seats were not too cramped.

Cons: Wifi that actually worked.

Cons: The flight was delayed for no reason given. The seats don't go back anymore-that sucks for long flights. To charge $2.99 for a soda that once was complimentary is insane! The bag prices are ridiculous. You trick people by offering ok prices for the original airline ticket, then charge outrageous prices for bags and drinks. Very disheartening. I will never fly Frontier again.

Pros: I am claustrophobic and prefer an end seat. My discomfort even prevented me from ordering drinks and food.

Cons: Charge for every possible essential after advertising low fares. Really uncomfortable seats, no recline, no head or neck rest. No wifi or entertainment on long haul flights.

Pros: Liked the price

Pros: The crew were nice and accommodating.

Cons: The seat was not comfortable, my back was hurting from a very short 2hr flight.

Pros: it's Frontier...just basic.

Pros: Crew

Cons: Uncomfortable seats, no entertainment

Cons: My flight was delayed 8 times. I missed a whole day of work and had to pay for another night in the hotel because of their delay. This is the second time in a row this has happened with this airline. Horrible.

Pros: First 3 rows

Cons: The pesty flyer with the fedora.

Pros: Nothing

Cons: Landing, temperature, passengers

Cons: Could give more time before baggage and check in. Arrived exactly one hour before flight and ohh my god........ Management however pulled some miracle....

Pros: First Class was nice but not worth the extra cost - my opinion.

Cons: First class, besides bigger seats and more foot room, was not worth doubling the cost of coach.

Cons: Flight got delayed by 2 hours without specifying the reason. Weather was fine. Happened 2 hours delayed. From DC to Boston too when I took flight on 12th. Will avoid AA flights in future

Pros: Friendliness of crew. Captains' explanation (on the return leg of our flight) of why it took sooo long to know why our flight was repeatedly delayed. Extra leg room seats for purchase.

Cons: Having to purchase my seat, paying to have a carry on and for EVERYTHING else- a la carte style!

Cons: Tight seating is horrible

Cons: Both flights were delayed. Crew attendees were nonexistent. Nickel and dime charges for everything. Would never fly with them again.

Pros: Nice crew.

Cons: Our flight was supposed to leave at 6:40 PM but was bumped back until after 8 PM due to storms in the landing city however two other airlines in the same airport heading to the same city left on time.

Cons: Plane left 4 mins early knowing that passengers were on a delayed flight.

Cons: Again, make sure to note conspicuously that luggage price is not included.

Cons: Connection at Schiphol often tricky;

Cons: Plane was too hot

Cons: There was no way for us to add another bag after our seat placement. No one answered the phone for Alligent and the website didn’t work. It costs $20 extra to do this at the airport. Even though it was not our fault that there was no one answering phone calls (and no way to leave a message)

Cons: Very dissatisfied with boarding and told we had to pay for our luggage but noone else did .I had prepaid for 1 incase I brought big luggage but I brought carry ones. So I was charged 100..but everyone else's was larger

Pros: Nothing is good on this flight. It was delayed by 7 hours and the communication is not proper

Cons: Customer service

Pros: We finally got to our destination

Cons: Uhh not boarding and then the pilot coming on and saying "whoops we have to deplane since the weather is bad." Really? Why not just delay boarding instead of putting everyone through that. Terrible experience

Pros: Nothing at all, I am never ever flying with them, worst customer service and they didn’t even complete all my connections

Cons: The customer service and responsibility to the customer. They left 13 people stranded in Dallas because of their mistake

Pros: Affordable pricing.

Cons: Selectivity in other customers. The lady in the seat in front of me urinated in her chair, which leaked onto my backpack and drenched it. I had to throw away my book, and rinse what I could. The pack may not be salvageable.

Cons: Needs reclining seats at the least

Cons: Deboarding took too long
