Ryanair
In answer to what can be done, the answer is simple. Anything ... that is safe of course. Right now, you can easily see that if you are a Ryanair pilot, the efforts you're making aren't working.
That's OK. Just try something else.
But the biggest roadblock for the Ryanair pilots isn't Mr. O'Leary, I think. It's the rest of the pilot group.
Plenty of them are perfectly content to sit back and let some other poor goof do the work, take the heat, be suspended, so long as they don't have to do the work themselves. But they'll be there with their paws out when the extra Euros or the days off come around.
That's not simply pilots though, that's part of every one in the world these days. That's a much bigger issue.
But I too digress.
How about a show of hands for the number of Ryanair pilots you guys from that company think you could actually muster to cause a ruckous - a safe one obviously. Would it be 10, 30, 50?
You don't need the entire pilot group, at first. Really.
What you need to get going is a handful of people with some courage and a plan. With a good tactical plan, you can create some awareness.
The goal shouldn't be to piss off Mr. O'Leary as much as to get some press that makes the passengers think twice.
A few really can lead the many, if they plan right.
