Route guide · Updated 2026
Pick the best of 3 nonstop flights on United and British Airways. But which flights let you stretch out, defy jetlag, and save hours door-to-door?
Our verdict
Defy jetlag
On shorter overnight flights, aim to find flights that are nearer or later than your usual bed time. This will help with dropping off to sleep.
The flights are also less likely to land when you'd typically be in deep sleep in your Denver timezone. Remember, you'll typically be offered breakfast 1-2 hours before landing too. That will feel easier nearer 6-7am on your body clock than 1-2 am.
Faster door-to-door
Most travellers will hit rush hour traffic en route to the airport. Expect the heaviest traffic in Denver from 3pm to 6pm.
If you depart Denver between 5pm and 9pm, you'll hit the traffic on the way to the airport and check-in. Taxis and Ubers will be more expensive too.
