Who gets the seat when the aircraft is full
By Neil Middleton · Co-founder, UnityTrip
Written for the person who was told no: the rotational worker bumped from the company flight, the dependant refused a subsidised seat, the traveller who turned up and found the seat gone. The rules are your operation's. This page explains what they are made of.
A seat on a company aircraft has no fare, so something other than price has to say no when more people want to fly than the aircraft can carry. On a scheduled airline the price does that quietly: the seat goes to whoever paid for it. On your company's aircraft a rule does it, and if nobody has explained the rule to you, a no feels personal. Under a well-built rule it is not. Five parts of such a rule decide your seat, and every operation sets its own values for each of them.
The five things that decide your seat
Priority. Each passenger type and trip reason has a rank. A medical movement outranks everyone. A crew change usually outranks business travel, which usually outranks private travel on the same departure. When you were refused and someone else boarded, the first thing to ask is which rank each of you held. The ranking is the priority matrix. If you travel on business, the seat has no fare but the trip still needs an appointed officer's approval, the third of the three checks in the seat allocation guide.
Quota. An entitlement is capped: so many flights, which the policy calls sectors, in a period for you, your group or your reason. Your remaining quota should be visible when you book. A refusal that says quota used means the cap, not you. The quota is what makes a seat with no fare fair to share.
Booking window. Some passenger types may book earlier than others, so that the seats a rotation needs are protected until close to the date. If you could not book yet, the window had not opened for your passenger type.
Displacement. When a higher-priority traveller needs a full flight, the lowest-priority confirmed traveller is offloaded, told the reason, and rebooked on the next departure. Being displaced is the rule working.
Penalties and go-shows. A missed departure or a late cancellation costs points, scaled by how close to departure it was, because the seat flew empty. Enough points can suspend your self-booking for a while; a colleague can still book for you. The seat a no-show frees goes to a go-show, the prepared traveller on the standby list, often minutes before departure.
