Tip: If the passenger was flying from London Luton to Barcelona Terminal 2 and staying at the Hotel Arisal. They will need a transfer from Barcelona Terminal to Arinsal (and most like a return back to the end of their holiday. In this case the first_leg of the journey is the journey from Barcelona Terminal to Hotel Arinsal. The passenger has a choice of pickup times. The dropoff times simply indicate approximately when that the passenger will arrive at the destination. The second leg times are for the return journey (from Hotel Arinsal to Barcelona Terminal 2). Once again they have a choice of pickup times and the dropoff times indicate (in this case) when they'll arrive at Barcelona Terminal 2).
