Tower R .
the vast majority of the eary mornig deps out of NI are quite full , not just BMI . Also a lot of the LHR pax are on company tickets , paid as a coporate rate which is less than the standard pax rate , again in this word pax numbers do not always equal profit . Each route is assessed over the whole spectrum and just because the yeild is high on one flt does not mean it is so for the whole route .
The average yeild on the 1st bfs/lhr ( when BA where here) was on average 79-87%
