Concur allows the ability to block certain airlines. This seems to be turned in by default for some carriers (probably they block the ones that pay lower commission). In other words, your company didn't necessarily request that those carriers be blocked -- Concur probably just did it. They can be unblocked. Your company just has to ask Concur to do it.

Also you can call a travel agent at Concur -- they are quite good in my experience! They may be able to see and book the ones that you can't see. They are a full travel agent and at the very least should be able to see all published fares. So you can price out your trip in matrix, and if it meets your company's travel restrictions, call them with the information at the bottom. At the very least, they should be able to get you that same fare. They may even have something cheaper.
