I am still none the wiser as to what the problem actually was which created such outrage ?
The lack of clarity on the issue seems puzzling unless the OP is worried that the disaster of not having the wine at the right temperature spoiling a 12 hour journey might be ridiculed.
Or were the flannels too late in the trip
FWIW I have had an EK Gold card for the last five years and have only complained twice and both about BHX baggage slugs taking two hours for offloading.
As to them going downhill, I disagree - they are surviving the downturn better than most and are not randomly cutting slots but are matching aircraft types to demand and not being dogmatic about it. BHX outward in May is quiet so they turn off a slot rather than fly half empty, but its back on in June, July and August when the demand is there.
Thats not failing, but really smart aircraft usage.
