@chgoflyer I think we interpreted the OP differently! I initially read their post as saying that they booked a flight with points, and wanted to change their return flight home prior to travel, and it was a 21,000 point increase (hence paying for the difference in fare, change fee info, etc). But re-reading it, it sounds like they were trying to change it on the day of travel itself, which is a different situation. I'm not nearly as familiar with same day standby rules, so thanks for explaining it! It makes sense now why there was such a large point variation. --Jessica
