My specific issue with FR is regarding their attitude to their customers when things do go wrong. You are left high and dry. I have never heard (or read on here) about FR showing any compassion/common sense assistance when things go wrong.
When you pay £10 for a flight, you cannot expect an airline to send an empty aircraft out to get you when something goes wrong. I concede, however, that this policy is different from other lo-cos such as easyJet. When there was an almighty schedule cock-up they organised a rescue flight back to London from Geneva (although many other flights were just cancelled).
FR do not do business with Travel Agents - they describe Travel Agents as "ticket touts who mark up fares and rip off our customers".
Passengers have the choice: if they don't want to pay a travel agent's fee and are capable of booking a ticket online, then they can fly with Ryanair. After all, that is the whole point of Internet-based transactions. There is no need for Ryanair to do business with travel agents when their passengers are perfectly capable of booking tickets online.
Finally, as far as contacting customer services is concerned, I recommend taking the initiative and addressing a letter to Michael O'Leary, Chief Executive at their Dublin HQ. When I did this a few months ago I received a reply within a few days signed by the man himself.
Some of you really haven't the slightest idea how a business works! I am not saying Ryanair is the perfect company, but you really do need to be a bit more reasonable.
