Have missed important interviews at the European

Have missed important interviews at the European Commission because of BA flight delays and mishandled baggage in December 2007 and foolish enough to fly with BA again on 16th December 2010 as was denied boarding a BA flight because 2 mins late to pass security at Heathrow Terminal 5 - reason being because someone from BAA wanted to try out a new security procedure on my hand luggage and lost my place in the queue...had tried to explain the situation to two BA managers who simply could not care less and blamed me for not passing security in time....other people working at the airport referred to this situation as being "double standards". i.e, managers do not treat all passengers fairly and consistenbtly when they have the discretion to take special action to enable a passanger to board a flight if late...the flight was leaving at 9.50am and I was at security at 9.10am and should not have had a problem getting on this flight but BA clearly did not agree....
