Vueling is having a flash sale until tomorrow, 19th of January. Fares starting from 9.99 EUR one way on Barcelona – London route. Travel from now till the end of March 2017.
There are plenty of other promotional fares to other European destinations, but inland Spanish and medium long-haul flights (e.g. to Africa, Russia, etc.) are excluded from this promotion.
Weekend in London or Barcelona for 19.99 EUR RTN sounds very appealing!
Among London airports, the cheapest flights are from/to London Luton airport. Note that Vueling now serve Barcelona-Heathrow route, but the cheapest prices there are not available. Also Gatwick is more expensive that Luton.
If you can be a bit flexible and travel of the weekday, you can have a nice weekend in Barcelona or London on the cheap!
Don’t forget that with each Vueling booking (even with the cheapest, promotional one like this) you earn Vueling’s loyalty points called puntos. And on Optima fares you can also opt in for earning avios.
