I do completely agree with you Yoshi, if I were the customer.

But since my main objective is to really learn Sabre, I left out a lot of details.

For example, if the customer were to order directly online, the air ticket will be much higher than what we invoice the customer (even though it was say class A), due to the requested date of flight, airline company and destination.

That being said, what my manager did, will it have anything to do with my manager's connection with the wholesaler?

i.e. there's an agreement of reserved specific seats etc.

Or Sabre has the functionality of 'locking' or 'hiding' history from subordinates etc.
