An airline has an algorithm to determine the priority of passengers who are wait-listed for a flight. It calculates a priority key based upon (1) frequent flyer status, (2) price paid for the ticket and (3) arrival time at the gate. The lower the key value, the higher placed the passenger is in the queue. The calculation is as follows: -If frequent flyer status is 'NONE', add 40 to priority key. If frequent flyer status is 'SLVR', add 30 to priority key. If frequent flyer status is 'GOLD', add 20 to priority key. If frequent flyer status is 'PLAT', do not add anything to priority key -If price paid for the ticket is $500 or more, do not add anything to the priority key. Otherwise points are accumulated for every drop in price. Each price range is $49. For every drop between $1 and $49 dollars, add 5 to the priority key. For example, if the ticket price was $310, add 20 points to the priority key. - The gate is considered to be open 1 hour prior to the flight. If the passenger is 60 minutes early, no points are added. For each minute closer to the flight time, add 1 point to the priority key Example
