5:00am flight out of Lisbon!

I don’t know if the airport ever closes, but according to their website for a flight within the Schengen you should be at the airport 90 minutes before your flight. My experience with early morning flights within the zone has been to arrive 1 hour before scheduled departure. If you’re staying at a hotel, the simplest thing to do is to have them arrange a taxi for you. On my last visit to Lisbon I paid the hotel for a discounted voucher. The trip to the airport from downtown Lisbon takes about 20 minutes.

No problems for a taxi. Second, this is a domestic flight, a solid hour or at most an hour and half at the airport is more than enough.

I've read about all the ultra early 6:00 a.m. flights out of Europe. It's bad enough taking a 10-12 hour flight without getting a net nothing sleep the night before in order to get to the airport on time.
But all of these flights drop you in a large European gateway airport where you sit for another 5-6 hours before a midday flight to North America.
Do yourself a favor in the future, and refuse any flight outgoing before 9:00 a.m. You will still meet up with your outgoing flight home.

Thanks everyone. I feel a bit better.

Donna,

As the flight is within Europe, I'd suggest being at the airport at least 90 minutes prior to flight time. I had an early flight out of Porto on my visit to Portugal, with a pickup time of about 03:00 as I recall. I asked the front desk staff to pre-book a Taxi for me, and the Taxi arrived before the appointed time. It was very easy, although a most unpleasant time to be travelling.

I’ve done this before. Simply ask your hotel to pre-arrange for a taxi. I’d ask about it upon check in and reconfirm the day before.

I too would be confronted with a 5:00 AM flight out of Lisbon this coming autumn. I am choosing instead to book an open-jaw flight, and will fly into AMS (departures later in the morning) and return home the following day, Delta-KLM-Delta. The option of a later flight departing to AMS and then home the same day leaves me with a layover too short for my comfort.

Yes, extra costs to incur, however, my well-being is worth it. I realize this approach isn't an option for the OP, just illustrating a different solution.

Happy Travels

Has anyone had to arrange a taxi or Uber without using a hotel? I’m staying at an AirBnB and my flight leaves out of Lisbon at 6:45 am.

Thanks!

If there's no recommendation in your guidebook, I'd stop by the tourist office and ask for a suggestion.
