There must be something with Aibus yesterday... AC 7 to HKG was delayed for 13 hours. Glad I travelled one week earlier, otherwise, I would be on that flight!

I think AC originally painted 13 A320 in Tango colours. As we all know, Tango did not do as well as they planned so they most likely just held off converting those planes to all Y config which is why you still see some J/Y Tango flying around. Also, some routes to Florida is not scheduled to start until early December so no need to convert aircrafts for those route this early.
