Most flights arriving from the East over the last two days have routed approx Ipswich-Bury St Ed - overhead or north of Cambridge - St Neots (even when no hold is required) before heading down to Luton, irrespective if there is anything inbound to EGSS or not.
It seems an unnecessary additional cost of fuel and time, especially when the more direct route (Ipswich-Sudbury-Haverhill-Duxford as used previously) has no conflicting inbound traffic to Stansted. So much for aviation reducing its carbon footprint, but I guess NATS wont foot the additional fuel cost or plant the trees to compensate.
