I have already received British Airways compensation in gift coupons. Can I apply for additional overbooked flight compensation?

Yes, you can apply and receive compensation for the denied boarding. Sometimes airlines give their passengers compensation in form of gift coupons or discount, but passengers have the right to claim compensation on the basis of Regulation (EC) No. 261/2004. Sadly, airlines usually give lower valued compensation in form of vouchers than the law defines. However, your compensation may be reduced in amount of those gifts value. You may check how much you are entitled to compensation with the help of our Flight Delay Compensation Calculator.
