One cubicle for 189 pax▸ . Let's say each visit takes an average of 2 minutes, then that's 30 visits an hour, or an average of one trip per pax every 6 hours.
You only need someone to be ill (not an uncommon situation on flights), and there could be quite an unpleasant situation develop.
As far as I am concerned, it is yet another reason why I will never fly Ryanair.
Even working in belfast for six months I avoided. The low cost scroates I rank as:
1. Flybe
2. BMI Baby
3. Squeezy jet
4. Die and dare
30-45 minutes is about all I can take. I can see how they have stitched up the really short haul stuff - the internals, the irelands, the near continent. But who in their right mind would fly as far as say greece with them. Go to spain instead!
