In the old days (20+ years ago) EMA had a great reputation for diversions primarily because the Handling Agents could access hordes of coaches at short notice (i think from Trent buses). So whereas aircraft went to BHX/MAN etc and the punters waited and waited whereas at EMA they just walked out and got onto the coach before heading off to LHR etc.
Now days its more of a problem if only because the ramps are full. 20 years ago it was the BMI Viscount and a Brit 737 if you were lucky!!
