Here are 6 more tips from The Traveling Professor:

Subscribe to the Flight Deals Newsletter:  Everyday they send out great flight deals.  The best deal I got was $1 (but $320 in taxes added on) from New York to Copenhagen one way on AA.  Sign up HERE.

Buy One-Way Tickets Only if There are No Added Costs:   Let’s say a R/T ticket between BOS and DFW is $298 but when purchased separately the tickets are $149 each way.   You want to purchase two one way tickets instead of one R/T ticket.  The reason is if you need to make a change to any one segment, the ENTIRE ticket is re-priced at the time it is re-issued which can be terribly expensive especially if the outbound flight is coming up soon.   For example, the day before an outbound flight I needed to change the return flight which was 34 days later.  In addition to the $200 change fee, to re-price the entire R/T ticket at such a late date made the price $760 more expensive because the outbound flight was leaving the next day.   But if the tickets were booked separately as one-way, the fee to change the return ticket it only cost $200 because the flight was 34 days later.

Insurance:  If traveling internationally, you must absolutely, positively have travel health insurance AND emergency medical evacuation insurance.   Not having it is insanity.

Insurance:  If taking more than one international trip a year, purchase health/evacuation and other travel insurance on an annual basis.

Get a Good Credit Card:  For instance, the MasterCard Aviator offers cancellation, interruption, baggage loss/delay insurance.  They do offer medical insurance but not necessarily medical evacuation insurance.  Also, there are no foreign transaction fees on this card, saving 3% per purchase.

Get Global Entry and Pre-Check:   Save yourself a ton of time and the anxiety of waiting in line.  It’s $100 for 5 years. And, if you get the right credit card like the Citi Worldwide Elite, they will pay for it.
