BuonaDomenica and mia

Maybe? is the answer.

Mia is correct that the TravelBank purchase does not fit anywhere within the stated offer terms but, after making a TravelBank purchase directly through United's website, I received both the Airline Fee credit and the AmexTravel credit. My data point is above (Post #216) and another user actually reported the same thing happening to them right above my post.

I have also made a subsequent AmexTravel bank purchase just in case Amex gets wise to their mistake and "corrects" it but it seems to be working for more people than just me.
