If nothing else, despatch reliability should become much better.
I have an ask, has anyone flown United out of Scotland? The reason I ask is that in daytime flights, the one and only United flight I took on LHR-SFO was mandatory shades down and darkened cabin from the end of meal service, as this was the preference for seemingly most ot the US passengers. It's a very different culture from BA or Virgin to although whom many shades are closed but ambient daylight os still prevalent. You often see US majors taxi-ing on long haul out with most of the window shades closed (it;s not an FAA requirement to be open for take off and landing). Are the Scotland flights also flown in darkness?
