Really good point - my company is encouraging people to book in advance and we always avoid 1st class when travelling for business.
I have heard a lot about empty peak time trains, with off peak services being rammed. The UK railways are not as bad as some for their focus on the '9-5 commuter', but certainly it was still an important demographic to them.
People are still travelling, but price sensitivity is higher, like you say and the trips have changed. What needs to happen is that Government, Industry and Unions figure out how they are going to make the railway more flexible and passenger driven. Maybe in the medium/long term we see the commuters come back in even bigger numbers than before, maybe we don't. Now more than ever we need to put evidence and long term strategy at the heart of everything we do


I do think the leisure boost has been due to the following reasons:
- People with more flexible working spend less time travelling during the week, freeing time and money to do more discretionary travel on the weekends. (This seems very positive from a social point of view.)
- We realise the value of seeing friends/family and visiting new places after the covid lockdowns.
- Long term trends towards rail for leisure - especially as these trips tend to be longer distance and even if it isn't quite as fast, people value not having the stress of driving, especially if it is their downtime.
