I was very disappointed with my flights to and from Newfoundland. I paid for Business Class seats because I need the lie back seats. Due to my disability, the Zone 1 boarding line in not applicable. We don't drink, so the lounge is not as desirable. The seats are the sole reason that I book business. AC decided to change planes, and I suddenly realized that I was on a plane that had no business class. My seat was comparable to the Premium Economy. I don't understand how AC can put you in the premium economy seat and charge you the fee of business class. On one of the planes, I didn't even have a seat screen. Even with the extras business class offers, they do not provide free wifi. It seems to me that if they don't provide a seat screen, they should provide free wifi. Although, the downgraded plane and seat is my biggest complaint, I also had to suffer the other typical complaints - the threat of a pilot strike, delayed flights that ended up costing me extra fees in transportation, and their precious business class lounge being closed while we waited the two hours for our flight. There is no direct flight to NL and I was surprised and discouraged to find that the same meal was offered on both flights. All in all, it was a very disappointing experience. It is not fair that they charge business class prices and provide economy priced seats.
