I am aware of the reliability of Wikipedia, however, is it true that easyjet (and ryanair) will be beginning service to Algiers from London Gatwick and Paris Charles De Gaulle (and London Stansted).
It states that both routes will begin on 2nd June (and STN on the 16th). Hoping it's true as I need a trip over there and flights are very expensive.
I am sure you can get to Paris pretty cheaply and from their look at Aigle Azure return Paris- Algiers can be had for around £145.00 including taxes.
