There was a time in the 1990s (as early as my history with Midland goes) when EMA-ABZ was served by British Midland on a 3x daily basis, I think with the Saab 340. Am guessing it was when they got rid of this type that the route was dropped. The latest attempt at ABZ which has been mentioned was the once daily ERJ-145 flight which tried to utilise the Embraer when it wasn't flying to BRU, and as mentioned, was a flop thanks to it's once daily frequency. With the extortionate T3 fares, a twice daily WW service would capture the market with ease, but bmibaby have neglected their home base for a long time.
