Low cost airlines search engine?

I use trabber.com or skyscanner.com it's not only for low-budget airlines but it finds the cheapest prices (at least here in Europe)

I find adioso.com interesting. I've not booked using it so far but have used it to check costings and flights. It provides rapid and easy access to information that others don't.

It has a (somewhat) natural language search engine (or a more conventional one can be used) and provides graphs of prices across date ranges. It highlights the cheapest flight in the date range selected both graphically and numerically. In the NZ-Asia region JetStar seems to feature a lot.

You can ask it questions like "AKL to CAN early October". I just had a look and they have made the search somewhat more formal with eg from and to boxes, but it is still quick and easy to use.

Probably not of interest, but within China I have made extensive use of http://ticket.9588.com/ with good results. They list all available internal airlines and allow you to see discount rates and number of seats at that rate for all future dates. Discounts of up to 70% AFAIR are available in some cases for early enough bookings.

Skyscanner even shows connections composed of flight segments by several low cost providers. This is a home-brew solution, which they name Multi-part bookings. Though impressive, it is risky: If the first flight is delayed (pictured: Ryanair) then you are not guaranteed to get the connecting flight (pictured: germanwings).

Mobissimo is a travel search engine that allows consumers to compare prices on cheap flights alongside hotels, and car rentals. It aggregates the results from over 180 online travel agencies, consolidators, and ticket vendors to show a side-by-side comparison of the best deals found on the web. It then redirects the visitor to the site with the best rates.

Other cheap flight search engines I am aware of include:

http://www.airfaresflights.co.uk/

http://www.dohop.com/

http://www.jumblefly.com/

http://www.kayak.co.uk/

http://www.dealchecker.co.uk/

Have you tried Cheap flights finder? They define themselves as a meta-meta search engine, because they compare across the comparison sites. They include skyscanner, momondo and some 800 sources for cheap flights.

I'm not aware of anything more all-encompassing than this one.

Low Cost Airlines saves money by only allowing you to book on their sites; that's one of the ways they manage to give you low fares.

With that said try the following to see if they show the airlines you want:

http://www.skyscanner.com and http://www.opodo.co.uk

try this search engine:

http://www.airtickets.aero

Results including European low cost airlines only

www.azuon.com specifically searches and connect low cost airlines. The program found many connections for me, esp. within Europe, that are way cheaper than what is available online with traditional search engines such as skyscanner or momondo.
