Find Cheap Flights from Washington to Denver

Pros: Price

Cons: I like to get to the airport early. It's always a gamble with what the TSA lines will be. So extra time get through and enjoy some food with no rush. Had to wait for over a hour just to check on our bag.

Pros: We were at the frontier check in desk at 5.40 pm to discuss options. There was nobody at the desk so we waited for 10 minutes.....nobody showed up. So we decided to call frontier airlines which. Took about more that 20 minutes and leaving leaving us no time to catch the flight. We told them that we've been waiting here andretimg to get a hold of a live person to talk to and now we cannot catch our flight since only 10 minutes are left now for flight to depart. They said that now I have to buy another ticket and all the flights are booked until Tuesday......I said what???? So....not our fault we could not catch the flight( which bra still have time to catch), but there is no waiting list or anything until 3 days? And that also I have to spend 3 times more to buy that ticket?? All they said is pretty much.....is "fuck yuu" Leaving is no other option but to book a last minute another airline flight costing us $850 extra. We were not considered as humans.....no regard, no help and no respect. WORST AIRLINE!! that is why I am not going to take my today's flight and will never book frontier again and would recommend everyone to never book frontier.....

Pros: Not a single thing

Pros: Our flight had a medical emergency during the taxi to our runway which the crew handled extremely well. That emergency delayed our departure, but it was understandable. There was also a seating mix-up with a handicapped person sitting in an emergency exit who needed to be moved to a new seat. As part of the shuffle, I went from my preferred aisle seat to a middle seat. The flight attendant offered me snacks and beverages as compensation which was a nice gesture.

Cons: Frontier can be a tricky airline to fly with. I have flown with them enough to know to pack light to avoid having a carry on other baggage. They also push their credit card deal pretty hard at the end of every flight which can be very annoying.

Cons: I am handicapped. Can't stand very well or for very long. I had to stand in line for over 2 hrs. They didnt open the check in until 2 hrs before boarding. Then it was almost 15 to 20 minutes for them to check us in once they were there. I was Furious over the $45 each for the 2 bags I had. Terrible s huh ock.. a friend had 3 bags and was required to pay $170... Had to pay for pop. Wow... the seats were tiny and no padding

Cons: I am in the military and was traveling with a ceremonial sword for a wedding because I was in the wedding party. The sword was placed in normal checked baggage, but never arrived in my final destination in Seattle. At the airport, there was no one at the front desk. After calling later, I found that the sword had made it, but I had to pick it up myself or be charged for delivery. The hours were awful at only two parts of the day in two hour windows. Preparations for the wedding made it difficult for me to make the times and I was unable to have it for the wedding. When leaving, I was able to get the sword back and I re-checked it to Washington D.C. this time in oversize baggage. Again in Washington my swords was not there and there was no one at the front desk to ask for help. Now I'm back in the same place waiting for frontier to get back to me to locate my sword. Needless to say this will be my last time using frontier airlines.
