It is interesting that
some airlines offer retirement travel benefits to retirees of defunct airlines such as Eastern , TWA, Braniff, etc.
Look up
Eastern Airlines Retirees Assoc
Similarly, check the participants in
ARPB
Lets face it, the cost of rebated travel is microscopic (extra fuel burn and extra paperwork; plus, some soft drinks?, an airline meal? )- service charges usually more than cover this.
It is not as though they were failed executives taking multi-million dollar golden handshakes.
