Jon Hamm kept the good times rolling as he boarded a flight from LA to NYC yesterday. The Mad Men star's been all over the map during the past week attending the Sundance premiere of Howl on Thursday then hit the red carpet with girlfriend Jennifer Westfeldt during Saturday's SAG Awards. Jon's been sporting a beard for the past month and most of you prefer it to Robert Pattinson's though we'll see if it sticks around for his SNL hosting gig this weekend.
