I tend to agree with Brian on this one in that a lot of these so-called 'budget' airlines are anything but. I too think that it is a damn cheek to start charging for luggage, especially when it is done in the name of "keeping the prices low for out customers" when prices aren't lowered, they rise as a consequence. I admit I'm not as familiar with RyanAir as with other handlers but in general, they all seem to have very similar M.O.s. Mel's point about the so-called "1p" flights is one - if by some sheer miracle you find these flights (that depart at 2am and return at 3am 17 days later) you then end up paying £25 or whatever it is for "taxes and charges" each way. Often it is impossible to get the cheap flights each way unless you are totally flexible with your times and don't mind how long you go for or what time you fly. To be fair to Ryanair they have been very good when I've flown Jerez to Stanstead (around €50 ret on a €4.99 ew offer) but only because I was totally flexible with the times I could fly and could cherry pick the offer flights. Easyjet are the worst of the worst for never finding the cheap flights they are constantly advertising.
However, I find the worst of all has to be Monarch - all they have done is increase their prices over the last 3 years, and become more of a nuisance as they do it. "We're becoming a budget airline!" they screamed, whilst promising to make flights cheaper, give the punter "more choice" and a better flight - how? By continuing to hike up their prices, by making you pay for all drinks and food on board (abolishing the free meal and drinks) and making you pay extra for leisure equipment such as golf clubs, skis and the likes. Add to that they clamped down on their excess baggage charges as well, now religiously charging for every gram over the 20kg allowance anyone goes (that's a point - what happened to the 32kgs limit?? You can only get it with BA nowadays). So flying with Monarch just got a whole lot more expensive - and minus food and drink! Give me BA anyday - they are not only often cheaper but you still get the food and drink, the service is superb and they are very flexible on baggage.
Anyhow, I have digressed - if Ryanair were in fact to lower their prices, rather than keep hiking them, they might have a case to introduce charges on baggage. Otherwise they are just ripping off customers by making them pay for soemting else that comes as standard with the airfare you pay to travel with any other airline.
