Here is the Official AENA website about Valencia airport in English. This site gives information in real-time of all arrivals and departures as well as full details of the airport. Please note that this airport is sometimes referred to as Manises. This is one and the same airport! Manises is, in fact, the municipality in which the airport is situated. It is a convenient 8kms/5 miles from the city centre.
Although Valencia is Spain’s third biggest city (behind Madrid and Barcelona) the airport is only just in the top 10 when it comes to passengers or aircraft movements as it falls behind the big tourist airports of the costas and islands. Nevertheless it serves over 50 destinations in Spain and throughout Europe. It as had an uneasy relationship with Ryanair but at the moment over half its destinations are served by the Irish carrier.
