This incident has messed up Delta's asian flight schedule. Today I flew Delta MCO/ATL/PDX/SEA. The ATL/PDX flt was suppose to be a MD-11 with the new Business Elite seats. The gate agent in MCO confirmed this when I checked in. Upon arrive in ATL, my flt to PDX was on a old L1011. It seems they have decided to use the L1011 from ATL to PDX. If you are flying form ATL to ***, your one-stop flt has turned into a plane change in PDX. Just another reason to fly less on Delta.
