If you’re connecting through Vancouver, allow more time than the minimum connection, especially if you’re heading onto a long-haul international flight. Weather and operational delays can happen, so build in buffer where possible. Download the airline app before you travel so you can monitor changes in real time, and keep essential items in your carry-on in case of disruption. If your itinerary involves a tight connection to an international departure, be proactive at check-in and ask about your connection status if there are delays. Having travel insurance or credit card trip protection can also provide additional peace of mind. Lastly, check terminal and gate information in advance, as Vancouver requires security and departure procedures for international connections that can take additional time.

United is the best! We love how easy TSA Precheck is at Denver airport. Our favorite shuttle parking lot is Pike's Peak, but Long's Peak is also super convenient. We do just carry-ons which makes customs at Cancun Airport a breeze.

We flew United Airlines and boarding went smoothly if not a little slow but we left on time. Arrive early at the airport as it gets very busy and crowded especially on the weekends.

Go early, it’s a big airport. There are two TSA screening areas, one might be more crowded than the other. From checking it to the gate give yourself at least 20-30 minutes to get there.

Also delayed. SAF road under ongoing construction for next several years. Car rental pickup is a disastrous 4 wheel drive off toad experience. Maybe flying ABX is better and then drive up to Santa Fe

Missed connection flight because denver air connections plane was delayed a broke

The crew handed out candy snacks, and water, which was great. However, the airport and airline are terrible at flying. Multiple delays on our departure flight and on return flight it was delayed so long that we missed the connection flight and had to drive home. Terrible service and did not get any compensation. All of their equipment was broken and they never tested it before the plane landed. We were stuck in Ironwood Michigan for five hours.

Denver air is great flight times and connections a little rough

Communication with delays. Failed to make a connection I ng flight in Chicago.

Excellent, from check Iin to arrival. I was apprehensive about flying a small plane between Ironwood and Chicago, but the flight and service was great. I noticed, after boarding , that my cell phone had little battery left. The flight attendant kindly lent me a charging device to keep me connected with my contact in Chicago upon landing. I will always remember that kindness.

Great snacks and friendly people for check in at Pierre SD!

The connecting flight came in 45 min late but everything else was great

Absolutely easy travels and no cost cutting by the airline.

Their snacks and hospitality was amazing. They offered full sized snacks. Im talking full sized water bottles, full sized snickers bars, gold fish, full sized canned sodas, what ever you wanted they took care of it for FREE. The crew was really nice and hospitable. I was honestly shocked

It was canceled. Supposedly weather. But there was no snow in Baltimore. At least we found out before driving to airport

I have not flown Southwest in awhile and had a very pleasant experience. From ticketing to boarding to the flight. The flight left on time and landed ahead of schedule. It won't be so long next time!!

The Southwest experience has definitely taken a dive from its early days. You can no longer deferentiate from other airlines. Air travel is too expensive. Southwest is no longer budget friendly. They have lost me as a loyal customer.

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Both of my flights arrived early and check in process was smooth

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

Flight was good but there are way to many announcements for credit cards etc.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..
