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.
If youâre traveling on an international flight, or with children, or have a disability or medical condition that could impact travel, please arrive an additional 30 minutes before your flight. If someone is dropping you off at the terminal, or youâre not checking a bag, youâll need a little less time.
