My understanding was startup costs for US and a big spike in training costs due to bro FO's coming off lock.
The Mx was not unexpected....those requirements are obviously predictable in advance. But there was a spike, some of which was coincidental with a lot of planes needing heavy checks or new engines. As the RJ ages we probably see more of that.
There was probably some winter Wx IROPs in there too.
