Does anyone know how strict the 5-day advance purchase is for the discounted TA ticket benefit? I had a change of plans and now would like to go in 3 days rather than next month. Thank you for any info. I was approved for purchase only a couple of hours after my request, even though it said allow up to 15 days, so that's why I wonder if the approval of this purchase might be quick too.
