I just booked a Lufthansa RETURN flight from Mumbai-Toronto, and then registered for Lufthansa's FFP, as I've never had a FFP before. I thought that as I was flying Lufthansa and registering to their own FFP, I'd get a lot of miles, but they just told me I'll get 5,000 miles, which is 25% of the total miles flown.

I know it depends on something called booking class, but I have no clue how to find the booking class of my flight, can someone help me? I have my e-ticket in the email.

Also, as I've not flown the flight yet, but only entered the FFP in the expedia website and it allows me to change the FFP, can I change it to some FFP which would credit me 100% miles for this trip?

But firstly, is there any FFP which would give me 100% miles for this trip?

Edit: It's L booking class
