I figured this would be the best place to ask this...
goalie-parents are flying SFO-FLL this coming Wed (Jan, 14) on UA1568 and when looking at the flight status, is see "Boeing 737-800
SFP | #3511". I searched the 2014 fleet update thread and came up with nothing and the current fleet listing for ship# 3511 doesn't show anything unique. Any info on this or is it just an anomaly?
