Do you mean that there were no easyJet aircraft at the airport or just at the listed gates? You will probably find that the aircraft were not at the "Correct" gates. The departure board (Inside the UT Programme) shows the real life times and gates that appear on the airlines schedule. However FS rarely will send landed aircraft to where they are meant to be. Try AFCAD.
Hope this helped
