I'm 3,100 miles short of what I need for our trip to Europe next year. Looking at the milesaaver availability on the AA website, it looks like seat availability is becoming limited. I'll have the 3100 miles at the end of this billing cycle on my AA Visa, but that's still 20 days away. What are the rules regarding "holding" your reservation/itinerary? Can you hold for 5 days, release, rehold, etc? Anyone have any advice for me? This is my first award booking. Traveling mid-May, hoping to get two 20k milesaavers to LHR, then two 30k milesaavers from CDG on the way back. If I need to, I will buy 4k miles from AA for $110, but I'd rather find a way around this. Thanks in advance!
