Do folks know if J class is also the bucket for *A upgrade awards on TK (e.g., using United miles to upgrade to business on TK)?
Also, looking at ExpertFlyer, there seems to be a married segment or similar issue with respect to J class for an itinerary I’m considering. For example, IST-SFO shows J4 but AAA-IST-SFO shows J0 for both segments. Does that mean if I booked the longer trip, I’d be able to upgrade the IST-SFO segment or not?
Thanks very much.
