Tomorrow I am flying JFK-BOS-AMS. I have enough time to visit the Sky Club in T4 (want to check off the lounge of my list) and it would be easiest to drop my bag in T4 and pass the security there, go the the club and then take the bus to T2. Is that possible?

Alternatively I could check the bag in T2 and take the Airtran and clear security in T4, but that is suboptimal compared to the previous option. I know there have been quite a few threads about moving between T2 and T4, but could not find anything about checking bags. Thanks!
