I have observed that in one huge terminal some people like to seat anywhere usually not close to gate. They also like to buy things at the other end of terminal. In result they dont reach gate for boarding. At departure time max 2/3 of planes capacity were boarded. Staff is reluctant to let plane go when people are “on way” to the gate. 2-3hrs delays were normal.
Since all flights were delayed and airline satisfaction dropped below 20%, I decided to split one big terminal to 3 “wing-terminals”.
Security zones have to be perfectly separated (including ready walls), and game restarted. Otherwise security zones will not update and pax will use wrong security checks.
I am testing solution now.
