This is currently being discussed among all pilots, and especially commuters who share your pain.
There are some training issues that need to be worked out and some captains and ops agents that are apathetic to the plight of the commuter. The weather recently is also a factor.
I will let the more experienced hands comment further, but I sincerely hope that this practice stops and common sense prevails. It pains me to hear about any commuter left behind because we are "weight restricted".
