I was wondering about posting a "What companies do you hate" thread the other day, with my company being Ryanair. They've turned hidden charges into an art form.
£2-3 each way, excellent, ah wait you have to pay tax and a surcharge on that of ~£15 each way (which I thought was illegal in law now), ah you want to check in then? Well that'll be ££'s too (even online), take anything but hand luggage and that'll be another £20+ and finally (by way of missing massive other tiny charges out) you want to pay (but don't have the least available card in the uk), that'll be ££ as well. All in all an apparently £6 flight with only hand luggage works out at £70...
Ryanair are by far the worst model for low fares airlines, however conversely easyjet are one of the best (although they do have their own little charges), they show the full price of the ticket straight away and charge less for more hand luggage, so although tickets are apparently £20+ each way they end up in fact around the same price. Unfortunately, although I avoid Ryanair like the plague I occasionally have to fly with them (no other airline flies the route), but even then I'm very tempted to pay the extra £20 and two hour travel time to get to Gatwick and fly via Easyet.
However one positive, once on the planes they are atually in better nick than most other airlines, mainly because their stock (like easyjets) is only a few years old, unlike BA's and worse still a company called Viking air, eugh.
