I believe that Easy-jets support of R3 is because it would cause such chaos at Lhr
Carolyn MCall was on 5 live earlier this week suggesting a quick decision on airport runways and LHR BUT I thought exactly same as Walnut.
If you plunge your competitor airline into what will be years of utter chaos would you not walk away smiling !
LHR WAS brilliant for what it has done over last 30 years but its location which was a blessing is now a absolute curse.
Everyone is talking "fast and loose" about putting another runway in as though this will solve the problem, the surrounding infrastructure around LHR road/rail required to reap the benefits is the major issue.
I don't personally think that can be solved.
