The second part of your sentence only covers a part of the story though, the other half being that the airport operators have shown a woeful unwillingness to provide appropriate levels of staff to cope with the increased number of searches. Now maybe you understand where Michael O’Leary is coming from.
At EDI, there is PLENTY of staff willing to come in for the overtime to help with the extra searches (and they have been). Unfortunately though, there is just not the space to do it. 6 staff on a gate is all that can be done.
I wasn’t nit-picking at your post, just giving a different look on it.
