What are good Airlines for travel to and from Portugal. I will be leaving the Southeast US. Iberia or Tap seem the most logical, but online reviews are not very complimentary of either airline
Do you have specific priorities that would single out one airline over another? For me, any commercial airline that has a flight at the right time of day, without a bunch of inconvenient transfers or connections, at a reasonable price, is the airline to use. Unless you're looking for certain "perks," upgrades, or special services, any airline is essentially flying you in a metal tube, strapped into a tiny seat. Remember that people with a negative review for a company are more likely to post that review than those with a neutral or positive review. Every airline has its share of bad experiences, but, again, it's something you gotta do, unless you're taking a boat to Portugal.
Are there many direct flights to Lisbon from the USA? I don't know, but you may have to connect through another European airport, and then fly on to Portugal from there, so it might involve more than one airline, too.
Between myself and my daughter, we've flown with American, British, Delta and United. I've used TAP and Iberia within Europe. There are few discernible differences. I use Skyscanner and look for best connections and cost. The shorter flights with TAP and Iberia have been fine. In fact, TAP has better service and newer looking planes.
Go with the best connections and price. There are new direct flights from the U.S. to Lisbon being added with Delta in the coming months both to Lisbon and Porto.
We are going to Lisbon in March and flying out of Bilbao. We found Lufthansa airlines from DFW have one stop in Frankfort and then to Lisbon. We will leave Bilbao and fly to Frankfort then to DFW . Last time we went we had layovers in two cities. We grabbed these flights but we have never traveled Lufthansa before. It is hard to get to Lisbon with just one stop from DFW, make that almost impossible, so we are taking our chances with Lufthansa. Don't know either Tap or Iberia. Good luck with your search.
We leave on our first visit to Portugal in a few days. We originally booked on SATA but they changed our return flight date and so we had to then book with TAP. There weren't any non stop from Boston to Porto, and any flights had several to many, many hour layovers in out of the way airports. Non stop from Boston to Lisbon red eye with a 1 hour AM layover, and then continue TAP arriving in Porto at 8 AM. Will be in Porto 5 days, then taking the train ride back to Lisbon for 5 days. Our return flight is non stop to Boston. The main flight is 7 hrs and change from US to Lisbon each way, and for the two of us, with trip insurance, it ran just around $1,200 USD total. Many more non stop options from NYC to Portugal, but coming from Downeast Maine it is a 1 hour commuter plane ride to Boston.
Last year we flew Boston -> Lisbon and then Porto -> Lisbon -> Boston on TAP. The flight was relatively inexpensive. The experience wasn't bad. Better than relatively recent intercontinental flights on Lufthansa and Air France which were just plain uncomfortable.
