I've been trying to take a trip this weekend using miles, but one of the flights was completely full. I set an alert on ExpertFlier and it just fired, and I was able to grab the ticket using 30k miles. The interesting bit is, ExpertFlier shows zero availability in any fare classes, both before and after I purchased the ticket... however I was able to get one. Is Frontier overselling this flight? Does anyone know how that shows up in the fare buckets? Do they stay at zero, but let you purchase anyway... or do they add inventory in Y/B and other high-priced fares? If it's the second option, then EF must be showing incorrectly...

On that note, being able to spend 30k miles to purchase a last-minute ticket which is going for over $950 right now at a total cost to me of $10 is an amazing benefit of EarlyReturns, and one that I very much hope they don't do away with. Right now that is a major reason that I don't switch my flying over to United, which has a better schedule on the route which I usually fly.
