I have searched but didn't find an answer for my problem:
How can I specify mutliple fare basis code in one single search process? (I know how to do it with
As an example: I want to specify a return flight from ZRH-TBS with two different fare basis code (either I fly with fare basis code one or fare basis code two, both with different airlines).
If I enter '/ f tk.zrh-tbs.WLN2PRO; /f az.zrh-tbs.LSPEU6' or '/ f ..WLN2PRO; /f ..LSPEU6' or '/ f ..WLN2PRO|f ..LSPEU6' as advanced routing code and search with flexible search, ITA will accept this query but will show me only the flights with the first fare basis (WLN2PRO). What do I wrong?
Some help would be nice! Thanks!
