I few them once, going from Gatwick to Dubin.
The seats on the plane were more narrow than the ones I sit in when flying Delta, yet there was more leg room. Perfect combination for me.
I was only going to Dublin for 2 days and had a normal sized back pack with me, which they forced me to me to check, even though everyone should be entitled to a carry on. Luckily I dumped all the unnecessary junk out of my handbag and was able to shove in my digital camera and accessories in.
Otherwise, the flight was fine.
