As for INI. Shame that their numbers took a hit, however, they should have maybe expanded more slowly.
That 1pw flight was half of the drop. Other half is probably caused by weather conditions. Canceled or redirected flights and probably fewer passengers on performed flights again because of the poor weather.
There is nothing to be worried about with few new flights added INI would again have double-digit growth at the year-end.
