Manchester getting the 489 seat A380 for three months although that in general happened ad-hoc last year. No doubt BHX will see the three class 77W's during this period
Airlineroute has indicated this in the past, but the 517 seat A380 still made regular appearances anyway.
Even if the 489 seat aircraft does appear, its actually more of a compliment to MAN as the number of F/J seats remains the same, its steerage that gets the seat reduction. As being discussed, its F/J where the real money is made. It just means the cabin crew get a nice rest area
