US Airways Dividend Miles (Pre-FlightFund Merger) - Check-in/Security times for BOS-LGA weekday am

What sort of check-in and security lines should I expect for the 7.30 BOS-LGA shuttle on a Wednesday morning? I will need to check in (luggage), and I’ll be in F. Would arriving at Logan at 6.30 be reasonable?

(It has been a while since I’ve done the early morning shuttle run, when it would have been safe for the taxi to pull up to the Eastern terminal at 6:45 for the 7:00 shuttle.)

I generally have no problem at that hour - but consider the possibility
that the TSA might not have opened the entrance near the Shuttle
check-in yet - this would add up to (in my experience) 15 minutes.

Another thing you might want to bear in mind is that the regular
security has a GP/CP line that is often kept closed unless you can
collar the ID checker and show her (I can't say "drone" can I) your
GP/CP card or FC boarding pass. I don't know if there is any provision
for other kinds of *G, though.

Thanks for the good info, violist. I knew that someone would have had to have experience with lines being 5 mins long or 40+ mins long (such as the AA terminal at that hour on certain days).
