It looks like the DUB route is off to a weak start as I predicted. If you compare similar times (circa 19:00 out tonight, 23:00 return and 06:30 out tomorrow, return 09:30) the following number of people are checked in:
Southend: 146
Stansted: 233
Luton: 313
Gatwick: 403 (this isn’t quite like-for-like first/last are later/earlier)
Hopefully the route will pick up, but the 06:30 departure and 23:30 arrival look particularly low as I suggested would be the case based on previous experience. This shows the critical need for a proper put-of-hours service to London.
But overall hopefully the wider FR operation will do good things.
