Aer Lingus 320's would be crazy especially when considering how late In the season it is to start selling 180 seats for next summer
A large amount of summer sun flights get sold over Christmas and new year and early January, so it is not late at all.
BE added capacity last year ex BHX for e.g. on routes where there were gaps in capacity and demand. Flying 175 etc. They see a demand.
I think we could very well see EI on these tracks ... as I suggested last week.
