[ok] Display opening hours on "Open new route" page

[NovemberCharlie]

Hi,

When opening multiple routes at once, I usually have multiple tabs open with open route pages.
However I usually lose oversight of opening hours and I would think it is a useful addition to have the opening hours in plain sight (in stead of having to open the slot pages for each airport).

I took the liberty to use chrome's "inspect" function to illustrate what I mean.

Cheers,

As someone operating a regional airline to little airports, the vast majority of which have curfews, this would be a wonderful addition to help the route planning. Often I'll have dozens of tabs open and it's not until I try making a route will it tell me the destination or arrival airport is closed at the time.
