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.
Domestic - 90 minutes before your flight International - 120 minutes before your flight BUT..if you're traveling on a heavy day (ie Wed, Thrus night, Friday, Saturday) during high capacity times (mid-day thru early evening) then show up at leastr 120 min early for domestic, and 160 minutes for international flights.
