Thanks Ben. I've posted a message, as you suggested. Because I booked through an agent I didn't realise the flight wasn't direct from Manchester until it was too late - I told the agent I wanted to fly from Manchester so that was what they arranged. I might have considered Bristol if I'd known before the booking was completed. Ah well, it's not the end of the world but just adds a bit more complication when you're not an experienced traveller.
