Well Skippy, I think you need a good dose of Cammomile tea.
I'm not advocating any "solution", merely putting a point of view.
A point of view I can only speak from my own personal experiences.
I've flown on enough B744s & B777s out of LHR two thirds empty & also flown many times in "J" from MAN at a substantially higher price than flying from LHR.
I'm not talking about a "struggling" LHR but some airlines "struggling" to fill their multiple schedules.
I don't have any answers, merely an opinion that the current slot system distorts the market.
I'm more than happy for you to hold a different view.
