Did the flight attendant say they were on an Ajira domestic flight? I was looking/listening for references to Oceanic airways but I didn't spot any.
No Oceanic reference but yeah, they were on an Ajira flight.
Other Lost references: An episode of Expose begins during the Ruby/Belle scene. Expose announcer is voiced by Lost co-creator Damon Lindelof, the Jules Verne novel "The Mysterious Island" is an allusion to the Island from Lost.
