I will not use the site again
I have just used the .ie version of this site to book flights with Aer Lingus and ended up exasperated. Although the correct details were displayed on the last screen at the paying stage, the confirmation email listed a different flight. The site Help phone people did not want to know and said they could do nothing. Fortunately for me the airline agreed to make the change with no charge. I will not use the site again.
