it will clog up the arrivals/departure flow though.
You'll have rattled a few cages there. Having flown the dash I can assure you it won't. Does it going into LGW? No. Being on a far superior jet now I have experienced both, the Dash's speed is much easier to manage. 230 to 8 was our best.
If its true I can't see it being a dash either. Couple of spare 195s lying around at the minute with more 175s to come.
