Iv'e been looking at Ryan Airs website and heard they have cheap flights, but I don't see any. Does anyone know how often cheap flights will come up? Are there any other airlines I should be checking on?

Are you looking at www.ryanair.com ?
What dates are you looking at?
Take a look at www.whichbudget.com too.

Define "cheap."

To where?

www.skyscanner.net

and when? The cheapest fares are pretty time-sensitive. The first to sell out.

There are no airline who gives you free tickets (at least everyday !! )

I suppose you talk about flights in Europe .. so if you are looking at around 30 euros tickets (with taxes) these are the cheapest ones but they are not easy to find, they sometimes make this sort of "sales".

the cheap ryanair flights do exist, but are often on tue-thur departures, and as noted, they do sell out quite quickly. You generally have to book at least 3 wks in advance to get those fares. Besides, stansted is a fair ways away from london and will cost a tenner to get there. be sure to check out flying out of LHR, or LGW. BA has flights ow that are about $50 to many destinations on the continent.

Don't forget - luggage weight can also be an issue on Ryanair. No good getting cheap flights if it costs a small fortune in excess luggage.

Everything and anything is extra on Ryanair. Not just luggage.

Fees for:
- using credit card to book tickets
- any checked luggage (more if you pay at airport, less if pre-paid with ticket)
- priority boarding
- drinks and food (including non-alcoholic ones)
