It didn't take long for the train to arrive once we were at the platform and we found seats easily and it was a smooth ride.

This is a review about a trainline that runs from DIA to Union Station in downtown Denver and while…read moreit isn't fancy, it's super convenient. Affordable, too. There are a few stops along the way, but the big benefit is the roughly 30-45 minute trip costs $11 (as of August 2025.) That's a lot quicker and less expensive than a taxi, rideshare or a rental car (and who wants to try and park anyway?) Plus, depending where you're staying and where you are going, you can not only walk around downtown and its nearby neighborhoods, but you can also take the light rail and other mass transportation to other locations. The trains leave about every half hour. Please make sure to purchase a ticket because employees will walk through and ask for it.

ATL also has the SkyTrain, which is groundside https://www.yelp.com/biz/skytrain-atlanta with only three stops (Airport, Gateway for the convention center and hotels, and Rental Cars). JFK has an Airtrain between the terminals and the rental cars that connects with the subway network. There are probably others I can't remember. We should review the train at Denver International Airport! Officially titled the Denver International Airport Automated Guideway Transit System, it is a people mover that connects the multiple terminals at DIA. It is located airside (inside the secure area) and uses two 1.25 mile tunnels underneath the aircraft taxiways and passing through the center on the concourse buildings. When the train arrives at a station, the outboard doors open first so that arriving passengers can exit, then the inboard doors open allowing departing passengers to board. There are four stops. Concourses A, B, C and the main Jeppesen terminal where baggage claim and ground transportation are located. It is the only option for accessing Concourses B and C; Concourse A can be walked over the pedestrian bridge. Interestingly, it uses the same trains as they do in the Plane Train at ATL. Plenty of room for standing, seating at both ends, poles and handrails throughout. It is designed for handicap accessibilities. [Review 19015 overall - 91 in Colorado - 2539 of 2022.]

Waisted 10 min of my time going over everything to not even explain why all of a sudden they couldn't do it right after I asked about delays. Are you not allowed to ask that??? I'm so confused!! At least provide an explanation & why hang up on someone?? I was polite the whole time so it's not like there was any kind of argument. Weirdest most unprofessional encounter. DO NOT RECOMMEND!!!!!

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.

Check in at the airport was easy. I was able to board with the first group. I was happy that I didn't have to pay for a seat assignment. Cokes were nearly $5 but free on my return flight on American Airlines. I was bummed there wasn't any movies on board. The flight was effortless and easy from DCA to my layover in Colorado.

Yesterday, April 4, 2026 I originally had a flight to Houston at 11:30AM. Houston was the layover to my final destination of Atlanta. At 10AM I was told that the first flight was delayed an hour which was going to cause me to miss the second flight. Myself and two other people approached the gate to resolve the issue and was told that the only option is a direct flight to Atlanta that doesn't leave until 10PM. I was immediately irritated because I had been there since 8AM and 10PM is a long time to wait. I respectfully asked if they could ask the flight in Houston to just hold off since we would be getting there late by 2 minutes. The very rude woman at the desk replied "if it was more of you but it's just 3 of you." So the three of us don't matter? Obviously what I'm asking can be done, but because it's 3 of us we don't have the option to try to make our flight that was inconvenienced because of your company! Truly disgusting. I was told my other option was to take the flight and "see if they can help you." While I understand that things happen out of employee's control, the attitude and the lack of empathy is what made the situation worse. However, that was not even the worst of it all. I sat in the airport a total of 12 hours just to get banned from boarding my flight. I came with a backpack that I always take with me, that fits under the seat, a personal item. I did not have a purse or anything else. The backpack was all I had, but being at the airport so long I had purchased a charger, water and food so I was carrying that plastic bag with my personal item as we were boarding. I was told to step aside to speak to someone about my bag. Not at the counter, or outside of the boarding area, I was standing at the entrance of the boarding area. After standing there several minutes and no one approached me I thought maybe she wasn't talking to me. After all, I have never had a problem with this bag. I start walking towards the ramp and a lady asked me to come back. I explained to her what I just explained to you and she said that my plastic bag of food counts as my personal item so I have to pay $99 for my backpack. I'm flustered because I fly allllll the time and everytime I'm in the airport I get water and snacks and take them with me. Not one person on 100s of trips have ever approached me about that bag! The lady already told me I had to pay, but continues to make me weigh it. As I'm weighing it, it now doesn't fit because I put the bag of snacks there. After she yelled for the 10th time "it's $99!" I said, fine, here is my card!! After I said that she says, "you're being loud and disrespectful so I'm not letting you on!" I never once raised my voice or was rude. She thought I didn't have any money and when I did she created another problem. I pleaded with her to let me on because I had been at the airport 12 hours and I needed to get home to my children! She wouldn't even look up from her phone. I pulled out my phone to text my babysitter that I might not be coming home and she goes "I was about to let you on but you're secretly recording me!" I picked up my phone IMMEDIATELY to show her my text thread and she continued to tell them to close the door.
