Tell me more ×  I'm member of the frequent flyer program Miles &
More. Now I wanted to request additional miles for a flight
during summer 2011 when I wasn't yet a member. To fill out the
online form, I have to enter the booking class. There are
various possibilities, for example Economy B class, Economy C
class, Economy D class, etc.  I don't know what this is. I flew
economy class, but I didn't know that there are any subclasses.
So how can I find the right booking class? The flight was from
Zürich to Helsinki with blue1.  share|improve this question add
comment  2 Answers  up vote 8 down vote accepted  The booking
class is the basis for the fare you paid.  Within the 'economy'
ticket section, there are different fare "classes", A, B, C, D,
etc, that have different price levels and a certain number of
tickets allocated. Different fare classes can also affect what
types of rights you have - like if it's refundable or
changeable.  So you could have 20 tickets in class D at €100, 30
tickets in class C at €150,
