Tight Seat (apt name!) but read the thread:
In the main cabin it varies between 28 and 29".

Hope this helps...
Look, I'm not trying to poke a snake pit of chippy Monarch stalwarts so I'll back out now. Thanks for answering my question initially. My only other issue was that I always thought Monarch were 'better' than the others and not to be grouped with the other lo-co's. SASKATOON was kindly pointing out my error!
I fly 3 times a year to Malaga and we always fly Monarch if we can and it's, more often than not, more expensive than the others, albeit not by much.
What I have only just realised, thanks to this exchange, - and the seat pitch thing is only one manifestation of this - is that really it is just another lo-co.
