DEN is a massive airport and as such navigating through the airport can be challenging, especially…read moreif you have a tight connection. This time it was extremely crowded, people everywhere. The terminal connector train was literally standing room only, a few people got off at a stop and a similar number got on. This left numerous people in the lobby waiting for their turn to get on a train. Unfortunately I'm very good at having connections in different terminals and this trip was no different. Get off my inbound flight, walk the concourse to the train, connect to the next terminal, walk through the concourse to my connection gate. To be fair that's not any fault of Denver airport. It also happens to me at Chicago and Atlanta. The terminals are clean and so are the restrooms. Lots of dining options and prices aren't sky high like some airport eateries. Denver will never be my favorite airport, but for a major hub it's far from the worst in my opinion. I'll definitely be back, hopefully less crowded next time.

I recently flew Spirit Air and honestly think they deserve higher marks than 1 1/2 stars. True…read morethere is a charge for just about everything on top of the low price fare, but they are very up front about these costs in their website. On any third party booking app it is clear there is a charge for carry on bags. Given that this is unusual, it should prompt the consumer to investigate further and it is not the airlines fault if consumers do not choose to do this. My only complaints were that checked baggage has a 40 pound limit or it is an extra $60. I have traveled all over the world and am familiar with the 50 pound limit put on luggage going overseas. This charge on a domestic flight seems like a money grabbing scheme to me and seems unnecessary given that it is out of line with standard practice. There was no food offered on my 3 1/2 hour flight. I could only get over priced, unhealthy snacks. It seems reasonable to offer some small, healthy fare on most flights and I was disappointed that this was not an option. Also charging for basic beverage service should be outlawed on airlines in my opinion. Dehydration is a serious concern and people should not be denied water based on ability to pay. They are not the most communicative of airlines. They should definitely put some serious money into improving their website, especially for online check in which is needlessly confusing. Now on to the good stuff. For an additional $45 I was able to secure a roomy and comfortable seat close to the front of the plane, almost like flying business class for dirt cheap My flight included a long layover and both planes were clean and new. We were delayed on the tarmac for an hour and a half due to weather. In all my travels this is the only time I have been cool and comfortable during a lengthy tarmac delay. It made all the difference to not feel like you were being cooked alive in a tin can during a lengthy take off wait. The staff were all amazing. Everyone I came into contact with was friendly and professional. They went out of their way to help. They allowed me a free carry on when I opted to bring my checked bag down to 40 pounds to avoid the $60 surcharge. This turned a nasty surprise into a positive experience. Even with the additional seat fare and higher than average checked bag cost, I still paid less than half of what the average going fare was to my destination making this an overall positive experience. Would I recommend Spirit Air? Certainly, with the caveat to travel very light and stock up in food and beverage before boarding.

I had insurance for Spirit Airlines, and I couldn't take the flight due to my grandkids was sick…read morewith Covid19 and the mother didn't want to let them fly so I had to cancel the trip, I was ok with it as I had insurance on the tickets, so I contacted the customer service to get my money back they said I can give you a credit back - I was ok with it then I was going to use the credit to go see my Grandkids in Florida (I live in Colorado) and when I was booking it there was no flights in Colorado I was like what!!!! then I found Spirit don't fly in or out of Colorado any longer. so I called and wrote Spirit to get a refund as they no longer fly out of Colorado, they said no they will not give me a refund I told how I am to use the credit if you don't fly in or out of Colorado it didn't matter to them so I have credit still of $1,177.77 and I can't use it. if anyone wants to buy the credit off me, I will be more then grateful I will take $800 for $1,177.77 - I really need the money as I just buried My Mom and it was a lot of money, I mean a lot of money. if there is someone on the Spirit team that can help me please I need my money
