Ive never used any kind of miles or loyalty programs though airlines. However, I just returned from a trip of ~20,000 miles (most of which were though Delta). I saw where Delta miles dont expire and I calculated that Ive flown roughly 50k miles with Delta over the past 4 years.
Should I worry about redeeming them? Their website wasnt working properly to redeem them so I guess I need to call. Is it worth it?
Thanks in advance for the advice, /r/travel
