It’s not just that when you add the time getting to and from airports, getting on and off the planes, and the time lost that could have been used to work, this argument does not stack up. These people are responsible for the rail services the rest of us have to put up with. There’s zero incentive for them to make the trains cheaper or more reliable if they’re allowed to fly whenever they feel like it.
Same for every politician. They should have to suffer what they put the rest of us through. Incentives, innit.
