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 have a cut-off time of 30 minutes prior to flight time in order to check in (we almost missd it once). To be safe, for domestic flights, we arrive at the airport between 1 hour to 1.5 hours prior flight time, which gives enough time to check in, and get through security lines. For an international flight, I would arrive 2 hours before flight time.
