Yes but remember Jamie EIR were expected to launch NOC long before they did. Placing the ATR on the DUB surprised a lot of people, then suddenly it was switched to NOC, like a planned move. BHD has been rumoured for quite some time, just watch this space is all I will say!
I suspect that NOC would of preferred Flybe to launch BHX before EIR and when BE wouldn't they came to EIR.
If you look at the schedule you will see why the extra flight times were selected.
Also noticed BRS-DUB has extra flights, randomly with a rotation that doesn't correlate to anything on their schedule, also priced way above other flights.
BRS-DUB was 3 daily last summer but released as 2 this summer and the 4 afternoon flights were added on Thursday (busiest days on the route). Until June the afternoon flights offer connections to afternoon T/A flights before a time change in July.
If we use you logic about the prices then the two recent MON routes launched won't operate and will be moved as the prices are way above the norm.
