Is there a way to "secure" a GDS reservation?
In general, when someone has the six number-letter combination reservation number aka. record locator and the last name of the traveler they can alter and cancel the reservation. Is there a generic way to add additional protection?
Edit: the answer is no and this is a known security problem.
Best Answer
A secret key of 6 alphanumerics is, in itself, reasonably secure. There are 2,176,782,336 possible combinations, making it (in combination with a single username) effectively unguessable.
There are a lot of infrastructure problems -- you have give the key to agents and CSRs, it is delivered by email, etc. -- but any secret of any length has that problem.
