As business travelers are usually on tight schedules and they want through the airport as quickly as possible, they might overlook some items that would make their stay at airports more comfortable. Granted! Business travelers are quick to buy a day pass for access to airport lounge or have access to some of them for free and these lounges provide them with food and drink, access to showers, WI-FI Internet and comfortable chairs.
However, when they are not staying at the airport for that long, they might be able to skip the lounges and for this it would be useful to pack some snacks in the carry-on or use an app like GateGuru to find out which shops and restaurants are available in each airport terminal to plan meals accordingly. GateGuru also provides weather reports, estimated security wait times, airport amenities and so on to avoid last-minute stress.
If you are a frequent traveler to and from the US, you might want to apply for Global Entry, a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States - it pre-qualifies certain travelers for expedited customs. Members enter the United States through automatic kiosks at select airports. Program members proceed to Global Entry kiosks, present their machine-readable passport or U.S. permanent resident card, place their fingerprints on the scanner and complete a customs declaration. The kiosk issues the traveler a transaction receipt and directs the traveler to baggage claim and exit. That easy.
If you get a combination of flying business class plus Global Entry status, you can just whiz out of customs and with your luggage right away.
Dress nicely even at the airport so you can get an upgrade or a seat. When flights are oversold, sometimes gate agents will pick people to upgrade based on whether they are dressed well or if they kick it off with someone at the desk. However, something as simple as elegant dress code - you should be wearing anywhere at risk you'd meet someone you are doing business with at the airport or on the way to the hotel - will maximize your chances to get a seat and even an upgrade for free so you can travel comfortably.
Airports may restrict the size of the liquids you can carry on, but what in in the container doesn't really matter. As long as it's under 3.4 oz, you can generally carry on any kind of liquid and that also includes mini liquor bottles. Enjoying your drink won't also take the edge off from how hectic and boring airports can be but it will also save you money in paying inflated rages for alcoholic drinks in the lounge.
Finally, as you make your way out of the airport, avoid long cab queues by detouring to departure. After collecting your luggage, avoid the massive queue outside arrivals by catching a cab in the departure zone where nobody is competing for cabs. As people are getting dropped off, jump in as they are jumping out.
