In the past when I booked with Easyjet to fly to Malaga I have entered my passport details online with the booking. However I have just booked a return flight from Prestwick to Malaga but I haven't been asked for my passport details, when do I have to provide Ryanair with them and how do I do this? I thought that the Spanish authorities had to have everyone's details before the flight left the UK.
Eh ?
You do this when you check in not book.
