I do not unless some external force forces their hand, e.g. the price of wheelchair escorts skyrocket, there is a shortage of them or turnaround time drastically nosedives with this as the root cause, etc.
As "unfair" or abusive it seems to the others, the current system is working for WN as is. If anything, the miracle walkers help with turnaround time at the end of flights.
The 35 in and only 3 out is nothing new or unusual today.. I have to believe they anticipate and account for this like "no shows", all 35 wheelchairs were NOT waiting for them at deplaning.
