What does "C1-4 NON END" mean on a Qatar Airways flight ticket?
score:20
Accepted answer
C1-4 : for flight coupons 1 through 4, inclusive
NON END : the coupon is non-endorsable, i.e. you cannot apply it toward travel on another carrier, so if another airline accepts it, Qatar will not pay them for it
CHNG PENALTIES AS PER RULE : change penalties apply according to the rules of the fare
These are common restrictions on discount economy fares.
