i'm going to thailand next month to visit my parents who are there for four months - so excited, but booking a flight was a nightmare. once i found something orbitz couldn't guarantee aisle seats, so i had to call air china, eva air, and thai air to find out if the seats were available. then, once booked, i had to call again to try and get the right seats.
all worked out in the end, but thankfully i checked out this site - http://www.seatexpert.com/ - before finalizing and found out my seats were dangerously close to the bathroom. no way, no how. got it all changed and am rearing to go. bless the internet!
