North first etc...... If its shorter cheaper than car and train so what!!!
I regular fly east to fly west i.e. USA via AMS
Travel agents probably offer NCL for the choice of available holidays, I am sure if the holiday was available from MME then they would offer it. They get the same commission! Afew years ago when Airtours went big time into MME they upped the commission to travel agents to sell MME every travel agent that year tryed to push mme first! Airtour's base is long gone from mme as is Thomsonfly's, says alot really!
