Dear FT,

First, a note to indicate that this site has been tremendously helpful over the last few years in squeezing value from my crazy travel schedule. Now, I'm not a newbie on DONE and AONE, but this is the first time I try the following itinerary. How does this look? I have a nagging feeling that the intra NA segments are no go, but would like to hear opinions. The other pieces I'm sure are doable...

BOS-GDL-BOS-DCA-BOS-JFK-HKG-DEL-HKG-NRT-HKG-LHR-BOS (or the other way, BOS-GDL-BOS-DCA-BOS-LHR-HKG-DEL-HKG-NRT-HKG-JFK-BOS

Thanks...
