First and Business Class passengers on the Emirates A380 can spend time during their flight socialising in the popular Onboard Lounge on the upper deck of the aircraft, while tasting fine selection of wines and spirits and gourmet delicacies. On a Reddit thread about the video, which has over 3,000 comments a contributor said: "I'm a flight attendant - the attendant is probably pouring the unused champagne back in the bottle before take-off to then dispose of once the plane takes off".
Kayumov initially wrote in Russian in the description of his video asking Emirates directly why the flight attendant did not pour out the champagne that had not been consumed.
Others noted that the flight attendant on the now-viral Emirates flight might have been saving the champagne for herself.
"Is it the norm to dump the undrunk champagne back in the bottle?"
International Business Times tried to reach Emirates airline for a comment, but there has been no response from the company so far.
It is believed the Champagne was a glass not taken during the airline's pre-departure drink service. "I asked a flight attendant on my last flight what they do if nobody takes the Champagne from them before takeoff, and he said they usually pour it into an empty container (I'm assuming bottle or something) and seal it for the flight".
The Independent's anonymous cabin crew columnist "Brad Bernoulli" weighed in with his own assessment.
One person commented: 'She should be commended for not being careless.
Another airline employee wrote: "There is no way they are taking it for themselves or saving it for later (against health codes, employee rules.)". Maybe it could have been more elegant if this action is done in the galley instead of the open bar'.
However, a flight attendant suggested the woman was probably just putting all the leftover liquid back in one place before getting rid of it later.
However, the airline itself has been less sympathetic.
'Actions recorded on this video do not comply with our quality standards.
Some insiders of the airline industry claimed there could be a perfectly innocent explanation, according to the Daily Mail. "We are now investigating the incident".
