Yes, though peanuts are still on some flights. When I flew from NH to Pittsburgh by way of Balt., I noticed we got peanuts on the way to Balt., but from Balt to Pitt., it was honey roasted peanuts all right (Southwest. Ding!)
On my way back I noted a video screen at Pitt. International Airport with helpful info for travelers from the TSA, as we stood in line to go through security. At one point it expressed the consequences one would face if they joked about having a bomb, etc.
oops that should say we were given PRETZELS instead of peanuts on the first part.
Then honey roasted peanuts.
