Does anyone know if Expedia, Orbitz, and/or Travelocity qualify for 3X points for $1 travel spend?

I am thinking about getting this card. I am a AAA member but do not bank with BoA...so Platinum Rewards bonus is out. I like the idea of getting 3% cashback for spend on airfare, car rentals, and hotels. From what I read on BoA's site, it looks like purchases directly from travel providers count as well as travel agencies count towards the 3X points, (which equals 3% cashback)...but I am not sure if that includes OTA's.

Any clarity would be greatly appreciated!
