It is probably worth pointing out at this point that airports are a business and need to make money. LCC's (such as Flybe) bleed the airports dry on both landing fees and service charges. If you (as the customer) want the aviation market to be open to everybody with low cost fares then you need to tolerate the queues and hassle that go hand in hand with regional airports - sadly, you can't have it both ways.
You will also find that while you also have anti-expansion bods (or NIMBYS!) putting a stop to any proposed project, airports will remain in outdated and confined facilities. Rather than grumble on PPRune maybe you could write to your MP asking them why the airport isn't growing fast enough to meet the needs of its users?
