So Fast Company has turned to travel expertsfrom flight attendants to hotel executivesfor tips on navigating packed airports, delayed flights, and more.1. You can fast-track customsIf youre traveling internationally, customs is often the first hurdle after deplaning. During peak season, the wait at customs can be more than an hour long, says Henley Vazquez, CEO and cofounder of Fora Travel. Using the customs concierge service to expedite the process is a worthy splurge.The service is available through some luxury hotelsVazquez says both the Ritz Paris and La Reserve Paris offer the service to fast-track travelers through customs and get them to and from the airport. She recommends checking if your hotel offers the service, as it might make a room upgrade worth the money.Outside of hotels, there are companiesincluding Global Airport Concierge and Royal Airport Conciergethat offer a fast-track customs experience as part of their VIP airport offerings.[Photo: simonkr/Getty Images]2. Major airports can be closer to each other than you thinkHoppers Berg says big hub airports like Hartsfield-Jackson Atlanta International, Dallas-Fort Worth International, and Denver International will be the busiest this holiday seasonand they had the highest disruption rates this past October. Some potentially good news: If youre scheduled to fly from a major city and your flight gets canceled, its still possible to travel from an alternate airport. If youre stuck at OHare, for example, Midway could have a flight thats on time. If youre stranded in cities like New York, Chicago, and Dallas, your ticket home may be just a train or Uber ride away, Vazquez says.2. Know what youre getting intoNigel Goode, chairman of London-based design firm PriestmanGoode, has been working with advocacy group Air4All to make air travel more convenient and less stressful for people in wheelchairs. The firms first-of-its kind airplane seat, expected to be installed in select airplanes next year, will allow customers to remain in their own wheelchairs for the entire journey. The process has taught him that its critical for travelers, not just those with mobility constraints, to plan each stage of the journey before heading to the airport. The more you find out beforehand, the less anxiety there will be on the day, Goode says.3. Essentials should be easily accessiblePaige Davis, president of AdventureWomena travel outfitter with more than 60 trips planned for 2025always flies with a small, easily accessible pouch at the top of her carry-on. In it, she packs earplugs, an eye mask, a pair of comfortable headphones, and a USB cable to keep devices charged. Ill also toss in a mini tube of lip balm and hand sanitizer, because comfort and hygiene at 30,000 feet are a must.[Photo: Getty Images]4. The airport can be a destination, tooFew know the highs and lows of plane travel better than flight attendants like Renae Grady with Alaska Airlines. Given the amount of time she spends in airports, she says shes learned to enjoy them. She suggests holiday travelers try to think about the airport as a destination on its own.Allow extra time for your trip so you can relax with a good book or noise-canceling headphones and a great playlist, she says. It can make the overall airport experience more enjoyable for everyone, travelers and airline workers alike, when passengers are more relaxed. Patience and kindness during this busy travel period can really make someones day, Grady says.Drew Richardson, president and CEO of PADI Worldwide, embraces a slower approach to holiday travel. My advice is to adopt an ABC mindset when traveling. In other words, always be chill. Part of the charm of travel can be the unexpected. Adjust your expectations situationally, be aware of your emotions in the present, and enjoy the experience, he says.5. Or you can avoid it entirelyPatrick Goddard, president of train operator Brightline, may be biased , but he believes the ease of getting on a train versus a plane is worth the trade-off in travel time.[Photo: Kohei Hara/Getty Images]Passengers get through security faster, keep their bags with them, andin the case of Brightlines in-route experiencehave charging stations at every seat and free Wi-Fi.Amtrak will have a fleet of new trains running between Washington, D.C., and Boston launching in the spring. Along with USB plugs and winged head rests, the trains will offer 25% more capacity. Theyre also quieter and faster than ever, running at up to 160 miles an hour.And if travel in general makes you queasy, staying home is always an option to save up for travel when airports will less busy. The best time to travel is during the shoulder season, AdventureWomans Davis says. The airports are less chaotic, cities breathe easier, and popular attractions arent overrun with selfie sticks. Bonus: Overbooking is your enemyAvoid filling your travel calendar to the brim, advises Fora Travels Vazquez. This can be tempting, especially if youre exploring a new destination or this is your one big trip a year. Try to set aside some time for true relaxation instead, she suggests, whether that means booking a full spa day or simply giving the alarm clock a rest. The last thing you want to do is return home on January 2 even more tired than when you left.
