"I do not like, however, that the airlines can add these fuel surcharges as they wish because there is no need for these in reality. Airlines can always change the fares as they please.

The only reason behind these fuel surcharges is that they collect them on award tickets, corporate discounts don’t apply for them and travel agents don’t get commissions based on the YQ amount."
