Las Vegas departures on this page leave from Harry Reid International (LAS) and land at Denver International (DEN). United, American, Frontier, Delta and Southwest have appeared in EazAir's fare checks for this route. Check the terminal before you head out: LAS puts United and Frontier in Terminal 3 and American, Delta and Southwest in Terminal 1. At DEN, Southwest and American arrive at Concourse C, Delta and Frontier at A, and United at A or B.

RTC Route 108 runs from the Bonneville Transit Center to Terminal 1, Level Zero, with stops at Sahara, Flamingo and Tropicana; United and Frontier passengers then take the free airport shuttle to Terminal 3. Uber and Lyft drivers use the departures curbs, as LAS has no designated rideshare drop-off area. LAS asks domestic travelers to arrive at least 2 hours early and to allow more time during major conventions. LAS says repaving in the airport connector tunnels is reducing lanes until about the end of December 2026.

After the train from your concourse reaches Jeppesen Terminal, follow the door numbers: even numbers are on the west side and odd numbers on the east. Uber and Lyft pick up at Level 5, Island 5, on either side, and DEN suggests requesting a car only once you have your bags. The RTD A Line to Union Station stops at 61st & Peña, 40th & Airport and 38th & Blake, and RTD charges an Airport Fare for trips to or from the airport.

EazAir's first 4 fare checks for LAS to DEN were run from 17 Sep to 16 Oct 2026. Each asked partner sites for the lowest one-way economy fare for one adult, 30 days out from the check date, and the highest result was at least double the lowest. Southwest, Delta and American basic fares allow a carry-on; the lowest United and Frontier fares do not. Search your own dates, and check the final price, bags and fare rules on the partner site before you pay.

Travel tips

Arrive early for domestic flights

TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.

Pack a mixed carry-on

Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.

Screenshot your confirmation

Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.

Check in online when it opens

Most airlines open online check-in 24 hours before departure. Checking in early can help with seat selection and, on some airlines, boarding group assignment.
