Not sure if @Rick&Jeannieis talking about an accelerated points system when purchased though the airline using a co branded credit card and
and having a higher lever of loyalty? Then yes, one or both of the things can lead to significant mileage awards.
We use miles as well. We are always looking to earn more. LOL. We look at EZ air, though. I like control of my own air. We frequently fly in advance of a cruise, sometimes more days than the allotted window and to a different city. For this summer’s trip we had EZ Air flights, but a few weeks ago, decided to book our own. The price was really good. And the mileage award was outstanding.
