Booked a ticket on the Thankyou travel site - but turns out it was AA Basic Economy. Regular Economy is only $2 more RT.

But it defaults to the lowest fare, and does not allow the blockage of Basic Economy.

Fortunately I read the red print after clicking purchase, and then immediately cancelled.

I guess you have to call. Not a good system if it defaults to Basic which is only $2 less.

Is there a way to block Basic?

On the phone with the booking people - THIS IS A MAJOR PROBLEM. Lots of issues with them booking as well.

THIS IS A HUGE ISSUE for CITI. Agents can't block it either. They have to go to a different system, and that doesn't work either. They only get the Basic Economy fare.

Been on a call with an agent for over an hour and she could not book - or did not know how to.

Result - only a supervisor can book. You need to use Expert Flyer to see lowest available fare bucket and tell them that, and the agent will then select that fare bucket.

Figure an hour per ticket to book via agent. (I have been 2hours)
