Alaska Pilot Cards
One of the first airlines to create pilot cards was Alaska Airlines. They are renowned for having some of the largest cards at 3.25” X 4.25” or larger. They also did not release the cards by set, but one by one as they came out. That has changed recently, but some of the older cards are very interesting to collect. You can also see their subsidiary Horizon Air here https://pilotcardguys.com/horizon-air
