Hello all... I will be travelling from Lisbon to the U.S. on April 30th via KLM to Paris, and then Air France to the US. My flight leaves at 5:40 am. Has anyone taken this flight? What time should I be at the airport? Oddly, I will be returning from Porto to Lisbon on the 29th of April. I had planned to check into a hotel on the 29th and depart on the 30th. Now, the flight leaves at 5:40 am. The predicament is whether to check-in to a hotel on the 29th in Lisbon if technically I won't be sleeping there? However, my biggest concern is whether I can get transportation to the Lisbon airport? I think I would need to leave central Lisbon around 3 am to begin my processing for my flight. Any thoughts or suggestions? Thank you,

your 5:40am flight from Lisbon to Paris would also be on AF, not KLM....
