Hi Viscount.
Just to bring you up to speed as I have only just noticed your Ryanair Dublin question.
GDS is showing 5 daily every day except Tue and Thu which are 4 daily for Dublin.
In terms of Tobago, its showing as 1 weekly from 29th October on Sundays with B767-300 and 'operated by Condor', though I suspect it will eventually turn out to be operated by a MAN based A330 as that amount of positioning will certainly dent route profitability.
Also, as there is still some time to go, I will expect to see much more schedule tweaking from all of the MAN based operators.
In terms of GDS preview, I'm learning now to take it with a pinch of salt after SV198/199 actually turned out to be SV123/124 on 2 different days out of the 3 published!
