This may be a simple question, but it matters as I'm trying to book some BA and alliance flights that will get me to at least silver later this year. If my tier point year ends on April 1 (just as an example), will a flight on 4/1 count for the old year or the new year? If it's a TATL flight that leaves the U.S. On 4/1 but arrives on 4/2, how does that count? Bottom line is that I can push back some BA travel so that most/all of it counts in my next qualification year but need to know if I can depart on the day my year ends and have it count for the next year or if I need to wait the day and have the flight occur entirely on the next day (4/2 in the example).
