I got a bit curious so started playing around with the schedules. It appears each aircraft will fly the routes below.
AC1 LGW-FAO-LGW-EIN-LGW-AGP-LGW
AC2 LGW-MUC-LGW-NOC-LGW-WAW-LGW
AC3 LGW-VIE-LGW-ZRH-LGW-MUC-LGW
AC4 LGW-AGP-LGW-OTP-LGW
AC5 LGW-VNO-LGW-ACE/TFS-LGW
DUB1 DUB-LGW-DUB-LGW-DUB-LGW-DUB-LGW-DUB
As mention above, NCE no longer appears to be within the network, which is a shame. But also could mean good things. Maybe NCE is the only route that EI are struggling on with U2.
And looks like DUB is down from 5 daily, which it increased to a month or so back. Again, perhaps this was just keeping the slots warm for this.
Anyhow, awesome news all round! Can't wait to try some of these services out.
