Another story regards them.
I had my own travel agency and used to fly to Mallorca on a regular basis,booking flights months in advance.
I received email from them saying that online check in was to be introduced,but because I had booked my flight before a certain date (I cant remember),I needed to check in as as normal.

Got to STN and there was lines of people waiting to check in,confusion everywhere

(I had got there early to allow for the obligatory pre take off pints!)

Staff just pointing to machines and saying have you got your boarding card,errr no,thats why I am in the line because I have a bag to check in

2 hours or more later after witnessing crying women and children who had missed their flights I got to the desk,gave the bloke my paperwork & passport and weighed my bag (12kg when I left home).

Bloke say's "where's your boarding pass and your bag is 18kg"....."dont think so mate and thats what I am here to collect,my boarding pass".....he then goes on to tell me blah,blah,blah....I told him no I had booked flight 4 months earlier and was told to check in as normal.....he pointed to the machine and said you need to get your pass and it will cost you an extra £60+ plus you are over weight with your bag.
"Well take you friggin foot off it then and you will find that it is 12kg"

"and NO I am not paying any extra"

By this time the line behind me was getting aggressive and so was I,security was called and I was ushered away from the desk

Pulled away went to Easy Jet obtained a flight for £40 and took off 30 mins earlier than the original!

Got back,wrote to O'Leary via the travel trust enclosing a copy of the email received from them,I received a reply from him stating that " as I was a member of the travel trade I should have known that checkin protocol had changed and that heavy delays at STN were inevitable"

Sorry for the long winded explanation,but the bloke and his airline can go get stuffed,yes people will fly with them for convenience and possibly price.
But I bet I can find flights as cheap if not cheaper in 80% of cases,something seriosly wrong is going to happen with these "low cost" airlines one day,25 minutes from landing to take off....it dosnt fill me with much confidence!
