Let me quickly stop you there. Frontier airlines here in the U.S. didn't have a payrise since the 2005 bankruptcy. They only voted in a new contract 4 months ago...and that's with a union. Go read threads about Atlas Air; another U.S. outfit with a union and one of the lowest paid pilots in the Nation. They are currently in court regarding a new contract that was amenable back in 2016.
Air Canada has no step increases for the first 5 years for FOs, and the basic there is as good as the guys who ask you if you would like that meal large.
