Miscellaneous Travel Information
DESPITE THE WORRY ABOUT RISING AIR TRAVEL PRICES, IT IS STILL POSSIBLE TO FIND GREAT DEALS, ESPECIALLY IF YOU HAVE PLENTY OF GOOGLE PERSISTENCE!
It helps immensely if you have some flexibility on dates, and can play around with them somewhat, plus travel mid-week can be more reasonable.
We recommend that you check into the frequent flyer program for the airline you choose. For example China Air is affiliated with Delta, so through their SkyMiles program you can accumulate almost 18,000 miles on a roundtrip ticket to Bali from Los Angeles. Affiliate frequent flyer programs can be found on the airline's web-site. Joining these programs is free.
