Low potassium (hypokalemia) refers to a lower than normal potassium level in your bloodstream. Potassium is a chemical (electrolyte) that is critical to the proper functioning of nerve and muscles cells, particularly heart muscle cells. Normally, your blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L).
If it's your first time to that airport maybe two hours for a domestic flight and three for an international flight. If you've been to this â¦airport before an hour and a half (maybe less if you don't intend to check bags) for a domestic flight.
The airlines usually expect you to arrive 90 minutes prior to a domestic and 2 hours prior to an international flight. If you're really tight on time tho, don't worry, because they usually call your name many times before departing. As much as it stinks, you should be there probably about an hour to two hours early.
