This is strange. All pax can avoid DVT if they just move about the cabin during a flt. You would be amazed however about the amount of people who refuse to move during a long haul flt. They seem to think that we are slaves for them to use during the duration of the flt. They will not even get up for a glass of water esp the americans. The phase thet we all hate is "I need some water?".
We all think, can you not get off your fat arses and get it yourself. Any English person would, they would not dreanm of ringing the call bell for a drink. They come and get it themselves. Sorry to all you yanks out there, but I have to say that you are all rude esp on LAX,LAS and SFO's. We all love doing MCOs and MIA because they are full of british tourists who dont ask for a think. God bless them.
