Booking class puzzle?
 

So, now that SK is in SkyTeam - how do I unpuzzle the booking classes (based on the marketing carrier) to know what the itinerary would earn?
For example, trying to price a JFK-DEL itinerary on GF. Seems to be ticketed by Delta. I can price it on Expedia and see booking classes per each segment. But are those Delata booking classes or each respective airline? (FWIW they seem to match neither and there is some additional messiness).
How do you, folks, deal with that?

GF is not a skyteam airline , so in 99% of cases you wont get anything

However it also depends on the marketing carrier selling you the ticket , which probably also added their codeshare on it

if that ticket will be purchased from delta and your FFP is DL SM then go to DL forum and ask , you might earn MQD but not MQM

if your FFP is not DL SM then you very likely wont earn anything

If you want to earn miles on this JFK-DEL make a booking and fly with skyteam airlines , period , unless you are not ready to deal with such topics like codeshares , booking class , exceptions , etc.....
