Low Cost Airline in Spain

Part of affordable travel is of course flying. With the cost of flying so incredibly expensive it is worthwhile seeking out the low cost airlines. Of course there is a risk that they will go out of business so my advise is not to book to far in advance with new or risky low cost airlines.

I just discovered an option for low cost flying with an airline based in Spain:

I checked out a flight from Barcelona to Paris (Orly) in June. The cost for two of us including tax return for a weekend was 180 Euros. Not bad at all.

Check them out and let me know if you have had any experience with them.
