I wish A/S coders will at least put an extra level of check such as "Are you sure you want to remove seats?", before action is executed!
Just yesterday, I lost AS$193,000 simply becos somehow my mouse clicked the "remove seat" button while I was busy scheduling (my laptop has very sensitive mouse). I ended up having to pay for the seats all over again!!
PS: There is a "remove seat" or "re-configuration" button option on the route plan page.
Don't you have to select remove seats option AND then press confirm?
