It's not just the "R" class.

Here's the fine print:
"Online check-in and booking credits will be awarded only for A, C, J, D, Z, Y, H, K, M, N, B, O, V or U fare classes."

Last year we had 2 of 24 (1 M and 1 N) This year'll be the same with more flights at bottom fare classes. I guess that this part of the 'Targeted' group is being incentivized to spend more for each tix which is not gonna happen here since none of ours is subsidized by a company. The only way we'll see more than the lowest Mileathon level is if our Chase Banker decides to comp the Mrs a Continental Airlines Presidential Plus Card.
