In BC I ordered the special “meat” meal and it was good. Usually the food in BC is not very good. In smaller planes the space in BC is a bit cramped. The Passport Control in Lisboa is terrible! A disaster! We will not be flying through Lisboa again. Because of Passport Control we missed our flight and had to make an expensive re-booking and overnight stay! Nevertheless, until the day of the flight, I received emails telling me that my ongoing flight from Lisboa to Valencia had been changed. Even though the whole itinerary had been cancelled due to the missed flight! We had had several TAP flights before, but we probably will not in the future.
