I used up my supply of vouchers last year, and fortunately or unfortunately depending on ones point of view, havent reaccumulated any recently. Anyway, in planning an upcoming mileage run, I have the following coupons that I am wondering which can be used in combination if possible. The wording is sufficiently vague (again fortunately or unfortunately) to argue either way. Anyway, here goes:

1. The $100 off coupon on a >US$700 ticket
2. Take 10% off on an economy ticket >US$125
3. US$25 Travel Certificate

My take is that 1 and 2 may be mutually exclusive, but that either one ought to be able to be used in combination with #3, which has typically been treated as cash.

I know that until I ask, I wont know, but what do others think or what has their experience been with these. #1 is a new item
so there may not be much history on these yet.
