Just back from the new World
Was burning my last BA Ex-Club miles (before they gave me another 10K for stress involved with almost strike).
Of particular note was the 4 1/2 hours we sat onboard on the ground at LHR on the 21st enroute to Vancouver. Seems they lost the key to the deicing truck (they couldn't have more than one at T5 could they) and with contaminated wings we couldn't take off before they deiced. We were offered one plastic cup of water, or an orange juice while we waited. Captain practically swearing in frustration, wasn't his fault was it.
I wasn't traveling in business, so can't say if they treated them better.
But at least they didn't cancel but they really need better contingency plans.
