my plan is and always has been to bring up my miles earnings to useable levels on all the airlines I have any with, and then BURN EM FAST!
I have already begun.
Sure I will fly again and maybe even use this tactic to better pick which airline I like more than not, but there will be a great hands-washing period in which I will have nothing and will not really care any more if the airlines change it all. I do now, but I fear the day is coming and we all must BURN EM (which is also maybe why the day is coming!)
