I tend to agree with you, Ian.
Interesting to look at the 5 year trend though:
Liverpool. 2009 283k. 2014 276k.
Manchester 2009 655k. 2014 756k.
Liverpool (no competition) net loss of 7k.
Manchester (both Aer Lingus and Ryanair in competition) net gain 101k.
Note that Ryanair is due to operate less LPL- DUB flights in either June or July than in February. In part that may be due to less football traffic.....but it does look odd.
