Flash Sale?
Lol, I just had one denied, and this is the reason....
The rate you saw was an Expedia flash sale rate; because this is a
promotional rate offered for a specific amount of time, it does not
qualify for the low rate guarantee program.
I emailed them back, that it is NOT a flash sale, is still available, and is available on other websites as well. I am not holding my breath.
At least they are quick to reply to my emails.... Here is their reply....
We went to both websites noted in your email and found both sites note
the rate as a "special rate". This would make those rates ineligible for
the low rate guarantee program.
