Well I guess I would say that it WAS an excellent program that slipped to Good and the jury is still out on where its heading.

For regular members the earlier comments sum it up - awards are getting harder to find. I'm a Silver Elite and had to have about a 1 month flexibility window to make my next vacation work.

For Elites its also getting a little tight. They put on restrictions that cut your Elite qualifying miles to 50% if you fly on discount tickets. (which even many business travelers get now with ever tightening budgets) There is an exception if you book on CO.com (but CO reserves the right to remove that exception at will and a lot of companies require booking through particular agents/sites). Additionally even if you do get elite status they shrank the FC sections to some of the smallest in the industry (6 seats on some 737s) so getting upgrades for that status is even harder.

I used to really brag about OnePass - it was so fun to mock the AA flyers having to ration thier stickers. At this point though I just don't know.

On a general level though you gotta give CO some points. They still have newer planes and bigger bins than most carriers and they are the last major that passes out something resembling food at mealtime.
