Hmm, an upgrade cert is good for 500 miles, and a transcon flight is about 3500 miles each way, so that's 7 certs each way = 14 which cost 100K miles or $560 for one round trip? Spending an EXP worth of miles for one trip?</font>
On a transcon where you would use 6 stickers each way, it is probably best to use the 30,000 miles and get the guaranteed upgrade.
