I am going to Disneyland in California in January!
I'm looking at flights and I'm really confused.
I'll leave from London and 2 friends of mine will leave from Rome and we'll meet there and do the trip together.
So I'm looking at prices both from Rome and from London to Los Angeles.
From Rome there is a flight from BA, leaving from Rome, connection at London and then to LA. It costs 502£
From London I can take the same flight from London to Los Angeles, but it's 609£
How is it possible that adding the flight from Rome to London, the flight will be 100£ less?
Would I be able to book the flight from Rome for 3 people but to checkin in London skipping the first flight?
