In the event that there is a problem when using the promotion, make sure that:
Coupon has not expired.
You added the coupon correctly.
You are using the latest version of the app.
Some other things to keep in mind:
You cannot apply the promotion offered in one country to another
You cannot apply two or more coupons at the same time, so select the offer you wish to use before booking your order
If the value of the discount coupon is higher than the price of a trip, you cannot use the remaining amount on another trip
Some discounts may have value in a certain percentage and thus reduce the price of the trip by a certain amount.
Some percentage-based discounts can have a maximum amount to be deducted.
If the above does not solve your problem, please contact technical support via the application.
