What’s the reason of the delay?

Attention customers of Orchid Air flight 7327 to London，I’d like to apologize for the delay，but it seems that we are going to have to change your departure time from 12:15 a.m.to 2:20 p.m. The plane is having technical difficulties that are beyond our repair，so we have to wait for the next plane to arrive. Again，I’d like to repeat that Orchid Air flight 7327 to London will now depart at 2:20 p.m. We apologize for the inconvenience. We ask that all passengers of this flight please proceed to the ticket sales desk so that we may better serve you. Thank you for your patience and understanding，and we will keep you updated should anything change.
