4. Allegiant Air announced that it has reached a tentative agreement with Transport Workers Union (TWU), which represents its 1,150 flight attendants after many years of negotiation. Tentative agreements, however, do not necessarily mean that the deal will be operational. They will be effective only on ratification. In fact, Allegiant and TWU had reached a tentative deal last year as well. However, it was voted down by the flight attendants. Allegiant will be hoping that results of the ratification vote are favorable this time.
