I think this is pretty cut and dry, but wanted to ask. I'm looking at a roundtrip to Tokyo in a couple weeks but desired return is waitlisted. My route seems to follow T-21 so I'm thinking to book confirmed awards with January 30th outbound (actual travel date) and February 3rd return(dummy booking). I can then on January 29th call and change the return to my desired date of February 19th(T-21). Does this check out? Thanks
