Almost all flying at Alaska Airlines just pays block. There are many individual examples of rig but the vast majority of us are just earning block. On the days of a trip where we are under-guarantee they take from the days we are over so that at the end we are at guarantee. common to block 1:45 on day one and 8:15 on day two for a 10hr 2-day. that starts at 0530 on day 1 and ends at 2345 on day 2.
