Remove all passengers from the plane that interfered and proceed with the deportation. Personally, I would consider it no different than removing a belligerent drunk from the plane prior to take off. Make it an official policy. If a passenger interferes with officers conducting a lawful deportation then that passenger will be removed from the plane, refunded their money and will have to make arrangements on their own for another flight. Rinse/Repeat.
Capitulation encourages ongoing behavior of this type and ultimately exposes a weakness in the authority of government to conduct such actions. Either government CAN deport or it cannot. If even a single individual can interrupt the process in such a manner than government abdicates its authority to perform such actions and cedes such rights to the whim of the mob. It also shows that the government lacks the WILL to enforce its authority in the face of even minimal civilian interference.
