Since I know you guys are exploring adding options to the store already...
What about adding in Delta airlines 1000 dollar giftcard? Living in the southeast United States, Delta is much cheaper than about anything else (since their hub is in ATL) and Southwest is practically non existent in the region. American Airlines is available but always roughly 20-30% or more than Delta and with less time options. Delta is the cheapest carrier in the region and to add Delta to the store may really increase the "airline" point sales.
Also, what about a 500 giftcard in addition to the 1000's for each airline, since most flights within the continental USA are 500 or less roundtrip? Thanks!
Just some thoughts, thanks!
