The access to London from Europe is pretty cheap if you use the low cost airlines (Ryan air, Easy jet and Vueling among others). For example if I wanted to buy a flight ticket from Madrid to London on January 10th, 2011, and assuming that it could be flexible on the date of my trip, the results in each of these companies would be:

• At Ryan air, the ticket would cost me 45.99 Euros on 10/01/2011, but if I buy my ticket on January 14th, 2011 it will only cost me 20.99 Euros.
• In Easy jet, the cost of the flight ticket on 01/10/2011 would be 43.99 Euros and it would be even cheaper if purchased on January 17th, 2011, it would cost just 19.99 Euros.
• In Vueling there is no direct connection between the two cities.
By the other hand, if I buy the ticket on British Airways on the same dates, it actually would cost me 158 Euros and in Iberia it would cost 183 Euros.
