unable to book the flight ticket with Error code: ar-40012. already log out and reopen and trial multiple times. also tried with a different price of fare, basic and flex but still end up with same error code.

update: Tried with another flight number but still getting the same error code

note: Contact travel agent and the agent able to proceed with booking manually.

would like to know how to solve this issue permanently.

@singkeat I wish I could tell you a solution, but I don't believe there is anything you can do about this error. I looked it up and we only have what the error code means, not any solution for it. 

Next time, I would ask the Travel Agency if they have any idea why this happens.

@KevinD may i know this error code is one off thing? or it will continue to happen to me on my next travel booking to different destination and different date?

just worry if this error will persists to hunt me until something done to solve it.

i have been using concur for many years and this is the first time i am getting this error code.

@singkeat see @EllenR 's response. 🙂

If you could share the flights/dates that you were trying to book we would like to look into why you got a repeated error.  This should be an isolated type of error where we are unable to book the same fare that you selected during the search.  This should be due to lack of availability from the GDS even though they returned the fare in the search results (GDSs often cache search results that may result in the inability to book the same fare once availability is gone).   You can DM the information to me to me if you would like.
