My yellow-tagged First bags were amongst the first off following LAX-MEL flight revenue F recently. Never seems to happen with BA anymore...in fact, backpacks and strollers are more likely to come up first on any carousel on BA flights before premium pax baggage! I was curious to note a First Class concierge (not quite sure what their title is) who met us off the aircraft and escorted us to immigration was also at baggage and noted the time of the first bag to arrive on the carousel, and checked that it was F tagged baggage.
