HOW DO I READ IT?
XXX-YYY DEC 4>5[4] JAN 4>5[4]
XXX Departure IATA code, YYY Arrival IATA code, Month, Average Departures/Day over the month for sale as of last week, Average Departures/Day over the month for sale as of this week, in brackets is the number of Average Departures/Day over the month that were scheduled one year earlier. So, it means that the listed airline changed the frequency between the two airports to add from 4 to 5 roundtrips in December and January. It also means that there were 4 roundtrips the prior year in each month. No other months were changed. I average two directions.
