Hi NewbieRunner
I tried some webpages f4freeJunior suggested.
checkmytrip and viewtrip were unable to locate my booking-reference.
virtuallythere.com could find it and there I could find an eTicket-Receipt.
This actually shows more than the eTicket itself.

It shows "Fare Basis: LSWISS" for the Swiss-Flight resp. "Fare Basis: TNN21G2S" for some segment booked at Austrian.

Now, I tend to assume, that this corresponds to L resp. T Booking-Classes.
This would also match your suggestion.

But where can I check this? - I tried to verify, but couldn't really find proof for this on a webpage.


Thanks in advance
