A few years back Wendy's had an offer where if you got a medium or large drink there was a coupon on it. 32 coupons got you a one-way flight in the continental US, 64 got you a round-trip flight. Being a poor college student at the time, a few friends and I went dumpster diving at all the local Wendy's and over a couple nights ended up getting about 4 round-trip tickets. The only drawback was having to throw out those clothes..
Wow i had never heard of this offer. But it seems like it was a good deal without even dumpster diving.
What does a Medium Drink at Wendys cost? Probably $1.50?
So buying 32 medium drinks would cost $48, which would get you a free one-way flight in the US. $48 (plus all the drinks you can handle and diabetes to prove it) is an insane deal for plane ticket.
By this logic a round trip ticket would cost ~$96 which is also a steal.
Even without dumpster diving, $48 is a great deal for a ticket even if you just dumped the soda out or never filled up the cup at the fountain.
