Confusion over arranging flights

[count]

I'm planning on visiting a school for astronomy, and I've been emailing the person in charge of this. I suggested flights which were cheap and worked great with my schedule. Instead, they got similar flights on another airline (Delta), but is much more expensive.

I'm really confused. Should I just go with it? It's not my money, it's theirs. I would have thought they wanted to save money.

I think some universities might have discounted rates on certain airlines.

As the other person said, they might have a bulk discount rate.

Also, some funding sources have restrictions on which airlines to use.

Or, maybe they just wanted to ensure that you get good treatment and didn't want you to use either a budget airline or an airline that is often late.

Or, they wanted you to arrive at certain times for other scheduling purposes!
