The Speech |
A phrase coined by PremEx that a passenger must give to the gate agent before a flight letting the agent know that the passenger is willing to give up their seat should there be a need for it (if the flight is oversold). If this is the case, the passenger offering the seat could be offered compensation (search the numerous threads to find what this could/should be), or an upgrade on the flight. Search this out as well, as you can see examples of exactly how it works! |
