Actually, If you read my post I said look for TWA to retire it's oldest MD80's in 8-10 years... Some of the TWA MD80's go back to Ozark days and were built back in the early 1980's. Same goes for some of the MD-80's acquired thru other sources. They will look to retire those as they will be around 25 years old at that time. Actually, They will be the oldest aircraft in the TWA fleet when that comes around and as time and cycles build so will the maint. on them.
