I have booked a flight to Penang from Heathrow and tickets are issued. I now wish to come back to Manchester instead of Heathrow, can I change return airport? This is called re-routing. It depends on two factors. (a) Whether the airline operates from that new airport you want to change it to, (b) Does the airline allow such re-routing. Some airlines allow it and some don’t. If it is allowed, then you will need to pay the change fee plus the fare difference between the flights from Manchester and Heathrow. Frequently Asked Question »
