Adler, here is what I experienced last week. I had a scheduled MEM-PHL-BDL. I deviated from the first leg only. (Acknowledged the same caution message). I joined the second scheduled leg at PHL. Per the contract I called scheduling to check in. They said they could not check me in until I was within 100nm of BDL (no protection just like if I had deviated from both legs). He said there is "no date" for the implementation of that portion of the contract and they do no have the software to do that type of checkin allowing you to rejoin the scheduled DH. Basically the only positive/advantage was the scheduled ground trans from BDL to the hotel stayed. I WAS NOT protected if that flight canceled since I "deviated" per the scheduler.
