Do you have 6 months validity remaining on your passport? Many countries require that your U.S. passport have as much as 6 months validity remaining for entry. If your passport doesn't have the required validity, renew it today to avoid the cost and stress of waiting until the last minute. Please see the US Department of State website for more information.
For all pending travel it's advisable to check your carrier's website for flight delays, cancellations and unforeseen events which may affect travel. Any cancellations due to weather, mechanical errors and acts of terror should be exempt from change fees and normal cancellation policies. Various carrier rules and regulations apply.
When traveling domestic or abroad, as a back-up, print paper copies of your boarding passes. You never know when your phone will be in a dead zone or Wi-Fi is unavailable. Also, most domestic and international hotels will print your boarding passes, some with a nominal fee.
When traveling on a multi-leg flight, whether domestic or international, make sure luggage is checked all the way through to your final destination. Double check your luggage tags before leaving check-in.
Most people, when they travel, are used to tipping when they eat at a restaurant but have no idea what to do for other tipping situations. Most professional service providers work for really low wages and depend on tips as the primary source of income. Here are some recommendations for tipping when traveling.
Restaurant wait staff - 15-20% depending on service. Don't forget about the buffet staff as well.
Hotel Bell Captain - $1-2 per bag. This can get confusing as one person unloads from the cab. The next person places it on a luggage cart and then passes it on to another. I wait until I get to the room and pay the last person who presents me with my bags.
Airport or train porter - $1-2 per bag.
Cab & Uber drivers - 10-15% of the fare. If they drive crazy or take me the long way around I do not tip at all.
Courtesy shuttle drivers - $1-2 per bag.
Hotel Concierge - $10-20 per request.
Hotel Doorman - $3-5 if they call a cab.
Hotel maid (room steward) - $2-3 per night. Sadly, only about 20% of travelers tip the room steward and these people probably work the hardest of all the people on this list. Plus, they really affect the quality of your stay.
Please let me know of other people you like to tip when traveling. Is there someone I missed?
