My jaw is presently on the floor. Not at the 200K number (I'll be doing about 225K myself this year), but at the fact that you did 200K wholly on CO, when CO does not offer any sort of tier or other incentive beyond 75K.
With that level of flying, you could have potentially reaped some significant rewards on a carrier offering tier and year-end bonuses. Even making CO Plat at 75K and putting the rest on AA or UA could have netted you some nice bonuses.
