Dear ordflyboy,
colmc is right, the short answer is equipment. i just flew TP from BOD to LIS (about 2 hour flight) in business class and the equipment was a regional jet EMB145... with two seats accross

Now, the good news, the business class cabin was empty (a total of three passengers) and the flight was during lunch time so a very nice and warm meal was served

Good look on your travels and try to find which equipment TP is using.
