This is the first time I've noticed this, anyone else? I hope this isn't a sign of things to come...
YUL-ZRH, random dates 28Jun-04Jul. On one routing YUL-YYZ-ZRH on AC421-878 one can see a single Tango fare. Incidentally, there are cheaper T+ fare available.
When you click through, the Rapidair flight shows Tango P and the TATL leg Tango T-class. However, the return, through YYZ, shows Tango+ T-class fares.
A quick search of other European cities (DUB, LHR, MAN, CDG, GVA, FRA, VIE, FCO, AMS, BCN, MAD) only displays Tango+, except for ATH which displays Tango fares (P, W & T) both out- and inbound.
I wonder if this is a glitch (e.g. UA/CO migration weekend) or no status mile accumulation on TATL.
I'd post screen captures if ever I could figure out how to do so...
