I'm flying United "round-trip" US to Lisbon with a separate "round-trip" flight from Lisbon to Palma de Mallorca on Air Europa.
When I arrive at Lisbon airport, I will need to pick up my luggage at "Arrivals" and then go to "Departures" to check in for my Air Europa flight.
My questions are:
Do I go through immigration and customs on both ends?
Are there "red caps" available to help me with my luggage (a big bag, a carry-on and a backpack)?
Are there carts to go from Arrivals to Departures?
How long will it take me to make this "journey" through the airport? I have a 3-hour layover.
