I am packing to head down to the ol' Helliday for 40 days and 40 nights (give or take

) of FO training, and I've got a heavy bag...
Will CO charge the rip-off fees for a heavy bag to a PS0'ed Non-rev like me? I can split my stuff into two bags weighing well less than 50lbs if I have to, but that would be an added headache.
Thanks!
