Tips for Dealing With Airport Delays

The good news is that as long as you remain flexible, you should be able to get to your destination. Using these tips can help get you there faster or with less hassle.

  • Call the airline immediately. As soon as the flight attendant announces a delay, most people rush the front desk. Use this to your advantage and call the airline directly from your cellphone. Not only will it be faster most of the time, but the entire ordeal will likely be calmer since the phone agent doesn't have to deal with other irate passengers in line.
  • Take advantage of airport lounges. If you'll have to stick around the airport for a few hours before your rescheduled flight, then take advantage of airport lounges. Many credit cards, especially co-branded airline cards, offer complimentary lounge access. You may already have one of these cards in your wallet. If not, you can always shell out the $40 to $100 to enjoy drinks, food and shower suites while you wait for your flight to arrive.
  • Check your wallet. Some premium travel rewards credit cards offer trip delay insurance on flights you book using the card. The benefit typically covers things like hotel nights, clothing and certain expenses like toiletries. Since most credit cards offer varying coverage, we recommend contacting your own credit card company with any questions about your coverage.
  • Get your money back. Even if you purchased a nonrefundable ticket, you can usually get your money back if your flight was seriously delayed. Airlines will typically offer to rebook at a later time, but if it doesn't work for your plans, then don't feel like you have to accept.


We used the last 12 months' worth of data available from the Bureau of Transportation Statistics, measuring from May 2018 to May 2019. To calculate the average departure delay, we took an average of each airline's reported departure delays over that same time period. Airlines were then ranked from lowest average departure delay to highest by airport. Please note that Virgin America has since been acquired by Alaska Airlines.
