Eastbound, in the winter, i use to constantly see speeds around 670-690 in the 320. Today I was supprised to see a JFK-LGB flight blocked at 5:05.

As for the 190, we do see it occassionally. If the inbound aricraft is extremely late and the outbound flight is booked under 100 they may add in a 190 if there is a free one sitting around JFK.

To the Delta 767 we where following in JFK this morning, if you are wondering where a huge, long rod from your aircraft went, check with our JFK MX Department as it found it's way through our right side main well tires.
