We booked flights NYC-Lisbon-Bucharest and back. The flights to Bucharest were fine. We thought it was going to be a great airlines. Then while we were traveling around Romania we were told through word of mouth that TAP Portugal had canceled all flights to and from Romania. They didn't alert us. No email, no phone call, nothing on their english facebook page. It took a lot of searching and asking people to translate for us to find from their Romanian facebook page that our flights were in fact canceled. Then we spent hours on hold and getting the run around from customer service as they rebooked our flights from different countries and with layovers that would have caused us to miss our connecting flights.
All in all a terrible airlines that you should avoid at all costs.
