Looking for advice. As I've written already, they have thus far honored one set of my tix despite not having all the miles deducted from my account. The problem is, the dating doesn't work for me, and I will have to pay my own way to go from TLV to HKG since those tix weren't honored. Therefore, I'll only use these tix if I need to go into the US due to a wedding or s/t similar.
So my questions are:
1) What are pros/cons to waiting to try and change the ticket dates, vs calling now and ensuring they can be moved without them catching the problem?
2) Is there a limit to how many times I can change the dates? Can I keep on deferring the tix for 12+ months?
3) If they tell me that the proper miles weren't deducted, and they will cancel the tickets, will the email they sent me confirming that the proper miles were used help me whatsoever?
