As many others have described, this airline does not allow people to drag onboard numerous over-sized pieces of luggage. That luggage will go into the baggage storage, and I am glad to see at least this airline pay attention to this sort of thing.
Overall comfort was about average, the crew were all nice, but very efficient as they only have but so much time between Spain and Portugal.
We had a slight delay departing Madrid, but that was due to the fog at the Porto airport, so no fault of TAP.
Our baggage was collected, we were charged the typical baggage fees, and we had no problems with our bags, they arrived in the Porto terminal soon after we did.
Some people have pointed out that there are no perfect airlines, and I would certainly second that suggestion. TAP isn’t perfect, but they are low cost, so you get what you pay for.
