AC (or IBM) should be shot for the problems of aircanada.com. This is so ridiculous that they still have inability for selecting fare class or at least eliminating Tango from the search after close to a year of people identifying the issue.

I was trying to book an itinery and they only give me N (Tango) fares and I cannot force the fare class in any form or fashion. I am too tired to deal with the Indian call center and reservation would not waive the fee. I think I will book another airline.
