Sipping an ice cold drink on the plane is a ritual for many when going on a much-deserved holiday.
But flight attendants have revealed there is one drink you should never order if you don’t want to slow down service.
They say that the pressure in the cabin makes soft drinks foam up much more than they do normally – with Diet Coke named as the “worst culprit”.
The flight attendants revealed that they can serve three other passengers in the time it takes to pour a can of Diet Coke on a plane.
An anonymous flight attendant who goes by the name Jet wrote on the blog These Gold Wings: “As you may know, the aircraft cabin is not pressurized to sea level, but rather to the equivalent of about 7,000 or 8,000 feet.
“This means some passengers might feel a little light headed or that alcohol effects them almost twice as much as it would on the ground.
“It also means soft drinks foam up a lot more when poured out of a can.”
They continued: “The worst culprit for this is Diet Coke. I literally have to sit and wait for the bubbles to fall before I can continue pouring.
“If all three passengers ask for Diet Coke I’ll often get them started, take another three drink orders, serve those, and then finish the Diet Cokes.”
The advice was echoed by flight attendant Heather Poole, who told Business Insider that “pouring Diet Coke is one of the biggest slow downs in the bar service, and on the shorter flights those precious seconds count”.
So if you want a drink served quickly – and to avoid making your flight attendant grumpy – it may be wise to choose another beverage.
However since the attendants revealed it takes longer to serve Diet Cokes, they have insisted they were not trying to put off anyone from ordering the soft drinks.
Poole even admitted: “For the record, I drink Diet Coke both as a flight attendant and as a passenger.”
And Jet added: “I don’t care what you want to drink. I’ll pour it, and I won’t have a second thought about it.”
