Coming back from the northeast yesterday on AA (finally), we landed in St Louis. As we were taxiing to the gate, I noticed an Aer Lingus 737 parked at one of the gates (kind of near the WN gates). It was green with the Shamrock, but I didn't see any name on the aircraft.
Who owns it, and what's it doing in St. Louis? Anyone know? (I did a search but couldn't find any info)
