That's a shame. I'd hoped UA would utilise a newer aircraft on this route to consolidate after the closure of IAD.15th May now bookable on United's site. Boeing 757-200.
Continental Airlines (predecessor of UAL) has in the past used a variety of larger types on MAN-EWR. The route was the preserve of DC10's for many years, later giving way to the B772 and the B764 each of which ran the service for a while. The B752 came alot later - and when it did the EWR schedule jumped from once daily to twice daily to compensate. More recently, it was decided to switch one of the daily EWR services to IAD instead.I seem to recall a 764 on one occasion which seems too big and the 772 would obviously be too big.
