AA still operates flight 1, JFK-LAX, what's up with that?

Flying into BOS last week, I heard FLG 3407 check in with final. I thought that I must be hearing this incorrectly?

Two days later we're inbound to BOS, the way our pattern worked out, around 11:30 a.m, when FLG 3407 checked in. I keyed the mic, and voiced my concerns about how disrespectful the use of this trip number is on the victims and families of Colgan 3407. Silence. I looked on Flightaware, and sure enough, 3407 operates daily MEM-BOS.
