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.
Usually for an international flight (out of europe) you should be there about 3 hours before the flight. for a European flight, u can be there 2 hours before the flight. But to be honest there is no point turning up that early unless you plan to go shopping at the airport, otherwise you will wait around for ages.
