Analysis
Excellent analysis David, thank you.
Have to say, I am one of the KLM passengers using NCL more. Including a trip last month and 4 planned trips, 4 out of 5 will be from NCL and only one from MME. Why?
Timings - better frequency and connectivity through AMS.
Price - At times, marginally better prices - though not always the case.
CDG - Whilst not a fan of CDG, I can outbound KLM and inbound AF at NCL (or vice versa) which gives me more options.
Whilst this doesn't affect my choice, NCL always run E190's or B737's whilst MME runs the old F70's.
Add the fact of the fee and the airport experience, you can understand why there is a move up North.
