Rumours on the EDI and GLA threads that FR have patched up differences with new EDI owners GIP and some axed routes are starting to re-appear in the FR booking engine from EDI. With increases from EZY, none of this will sadly help BHX to catch up with EDI.
However, as for domestic pax from EDI, according to the site of truth Wikipedia, in 2011 7 out of the top 10 routes for pax from EDI were domestic (BHX 7th with nearly 289,000 pax). LHR and LGW alone accounted for around 1.9 million annual pax, theres also LTN, LCY and STN to add to that! With such hefty flows to LON, BHX can hold its head high that with a much smaller domestic market, far more of its annual pax throughput travel internationally than from EDI!
