Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.

That's good to know that UA (probably many airlines) have information posted about DVTs.
While we all are concerned about flying and risk of DVTs remember that just sitting at a desk all day can engender the same risks.
" prolonged periods of immobility (such as travel in a car, train or airplane, or even sitting at your desk) can increase the risk of the formation of clots"
I had a few jobs in my lifetime where sitting at a desk for hours was the norm----- even insisted upon. (grin)
Have a safe trip, elsners and I hope your trip isn't for 'bereavement' reasons.
The information isn't for death only but also for hospitalization and hospice. So it might be helpful for our loved ones or loved ones coming to see us. Unfortunately it's only 5%, so not much of a deal. perhaps better searches may yield better results. Like" Google Flight"
That said, though, my parents, sister, and I had to fly suddenly to Ohio in early December for my grandfather's funeral and 5% off of more than $2000 in airfare is nothing to sniff at. At the very least, it's a couple meals out while you're on the road. Better than nothing, anyway.
I used to work with airline fares and went through the process when there were 'bereavement' fares (which they actually renamed 'compassion' fares since they did extend to more situations than traveling to funerals. Honestly it was pretty uncommon for those fares to work out better for customers than a normal fare. Especially after Delta kind of changed the fare advance purchase requirements a few years ago and other airlines followed suit. For most customers, it was possible to get a much cheaper 'normal' fare, the only exception being if planes were already nearly full or they needed lots of flexibility in their travel (like if they had no idea when they'd be returning), and even that wasn't so necessary after one-way pricing became more common at 'tourist' rates. Hope your trip goes well, Elsners.
