My Credentials: 9 YYZ-LCA AZ 8 YYZ-BUH KL 4 YOW-HNL NW 3 DXB-YYZ SU 3 KUL-YYZ DL 2 SFO-AKL UA 2 AMS-PVG AZ 3 XXX-XXX deal that never made it to FT 2 XXX-XXX deal that never made it to FT couple of others I probably forgot My Methodology 1. I assume that any given mistake fare will be SHORT-LIVED regardless of private emails/website, secret-codes, other 'preservation' schemes. Therefore..... 2. I book 'mistake fares' FAST, damn the wife, the job; finding dates that will have the LEAST PAINFUL consequences downstream, NOT time-consuming planning/research about IDEAL dates. 3. I assume that date changes and refunds won't be possible and am prepared to take the financial hit if the dates just don't end up working out; so I can book without the agonizing cost/benefit analysis My Expectations 1. I give the airline the benefit of the doubt that if they discover their mistake and contact me within a reasonable time frame (considering all the software they have, 48-72 hrs is enough time for them to find/react/contact), I will happily agree to refund the fare with no additional consideration. As I would want to be treated the same way as a business owner. 2. Airlines have better anomoly fare detection software and some embedded lurkers at key travel websites, so I expect fewer mistake fares and shorter windows. My Perspective 1. There are enough terrific fare sales and bonus promotions and that are indeed published with reasonable durations which should be the basis of your quest for maximizing miles and/or status. That is where the value of Milepoint can be leveraged.....crafting EXISTING information into creative, compelling and no-risk sharing earning strategies. 2. Many mistake fares were not ex-North America, so they are inherently self-limiting to those who have BOTH time and money. So, in most instances, if you are not privy to more mistake fares than in the past, you are not missing much.
