I think Avis should not have changed to the shortened expiration in the first place. It was not good to shortchange the most frequent customers on the benefits they already earned.

Then the whole some expire 1/15 , some expire 2/28 was just crazy.

Now, the good news. I just looked on my AvisFirst, it seems that they changed them to the original 6-month expiration dates! Finally they did the right thing ^
