Nice Premium Economy deal with Air Canada between Tampa and Lisbon, Portugal which is a lovely city see our Trip Report here and serves as an excellent gateway towards the rest of Europe.
The good thing about this sale is that the TPA-YYZ-TPA segments book into Premium Rouge which is similar to domestic First Class or a similar seat to the long haul Premium Economy seat.
The fare books into Z class for TPA-YYZ-TPA which credits from 100% to 200% and A class for YYZ-LIS-YYZ which credits from 50% to 125%.
