I have paid for return flights for three people to Edinburgh. We are going for a specific event and to save money I booked the 8.30pm flight to come back straight after the event has finished on Saturday night, rather than have to pay for another night's accomm. Naively I have now found out that there is an outside chance that the event may not finish until 8pm meaning we would miss this flight. Easyjet want to charge £45 per person to book a different flight back. If my partner went onto the website and made a brand new booking for single flights back home, would they cotton on to this as they do have his name as part of the booking I made? Any advice would be helpful!
