In the same order, Flybe introduced "return check-in" whereby a PAP checks-in for his day return at the same time as his outbound flight. The result: you end up waiting at the gate at, say, 1800Z for someone who may have checked-in at 0630Z in the morning! These are usually business people, but how can they be sure that they'll make their return flight? Then we have to wait until STD-5 before offloading them.
Also, Flybe procedures say that the handling agent HAS to accept LMC PAX until STD-10; the dispatcher is not asked, rather TOLD, that an LMC is on his/her way to the gate! What about the day when the aircraft has a few empty seats but is overloaded? We will have to refuse boarding (the check-in staff have no indication of what the underload is).
Mad...
