Four sectors on TP all now posted in 48 hours. The booking classes - in business remained a mystery until I saw the posting however I think if you book on Expedia you can see the booking class which you can't on the TAP website or on their tickets.
FWIW I thought TP and LIS were way below A3 and ATH on every front, the food was particularly awful and the lounge at LIS dreadful - I noted A3 use a contract lounge there which looks better than the TP one and certainly has better reviews.
