This in the scheme of things is terrific news for Prestwick, and it is what the people of Ayrshire and South west Scotland need, holiday flights to destinations in the sun. Edinburgh will always pull more visitors than Prestwick and so it makes sense to adjust the flights in the way they have.
PIK know that families going on holiday spend money, this should create extra revenue for the outlets at the airport and would explain why they have gone ahead with the departure lounge extension whilst simulatneously laying people off. The frontage and road area at the front needs some thought now as it all confuses many people with a maze of doors and roadways, and as mentioned before the rail station needs some tlc as it is a big asset to the airport.
What they need to do now is concentrate on is giving the entire place a good lick of paint as it looks run down in quite a few areas, and improve customer care for this all costs virtually nothing to the airport but it is what people remember and would hopefully encourage repeat business.
