The problem is, even though it is domestic there still isn’t a great amount of people travelling currently. Optimising a schedule for day visits etc is difficult under those circumstances. I don’t see that changing until things start to get back to a degree of normality. I.e people going back to work.
At the moment, the pent up demand is for leisure travel which is being trounced on by the uncertainty surrounding where we can and can’t go which changes on a weekly basis. Combine that with very weak business demand (which a lot of domestic is) and you can see the awful predicament the airlines are in at the moment.
