Seems to look like there could be one or two filler routes in there after the 1st & 2nd rotations.
Going to the comments about the Cardiff route.
Cardiff had 3 x daily Dublin by RE/EI for a few years along with a 1 x Daily Cork and at the beginning of the Cardiff operation a Galway & Lorrient.
Cardiff could and does warrant a 3 x daily Dublin service which will allow more opportunity to connect with Aer Lingus traffic at Dublin. RE/EI has been changing the schedules around for many a year from Cardiff. Take it now for isntance Mon-Thu the last flight from CWL is at 20:45 Fri & Sun is 16:35 Sat 11:35
I am glad to say however that from the summer the schedule will be fixed Mon-Fri.
When the RE/EI franchise agreement was announced they offered times which were very convenient for business traveller to allow a full day at either city and with 3 x daily it allowed for the leisure traveller to have a dinner time flight along with the business traveller only needing to go either direction for a meeting etc.
RE/EI have no competition for such routes at CWL compared with the competition they have with Ryanair at BRS meaning that they will have to charge less from BRS to offer reasonable fares. (Lower Yield). At CWL they can maintain their normal ticket prices and attract a (Higher Yield).
Maybe the ATR72 is slightly too large for 3 x daily but certainly the ATR42 will be ideal for the route. Also RE/EI could bring back the ORK route which did quite well for leisure travellers especially since the ferry service from Swasnea to Cork has now terminated.
