Today's (1/23/09) flight 36 MCO-EWR shows all exit rows available - and nothing else. On checkin, all the exit seats show no longer available after selecting and accepting the exit row terms & conditions. CO.com support says that nothing is wrong, all those seats are actually available. They said that in order to select one they'd have to uncheck in first - told them no as losing the existing aisle seat due to what seems a glitch would not be acceptable. Going to PM CO Insider with the PNR info.
