I have a ticket from Larnaca Cyprus, via London to Houston. I no longer want to start my journey in Larnaca as I will be in London. Can I just get on the plane in London after the 10 hour layover at Heathrow. It's also a change of airline but on one ticket.
The vast major of airlines do not allow this, but rather require you to have your ticket changed in such a case. They will cancel your ticket in case you don't show up for your first flight.
