Use of the word bias suggests that travel agents are acting unfairly or irrationally towards MME.
There might be any number of reasons price, previous customer experience (i.e. you offer 10 customers MME 1st then NCL 2nd and 9 of them chose NCL, what would you offer customer 11??), timings, etc
Might be useful for FoDTVA to do some (unbiased
) research to find out whats going on.
