Currently when one of more airlines offers new flights, you get an indication (green circle on the flight planner button). However when you open the flight planner you don’t see which airlines are offering new flights (just the total number of flights each is offering).
If you are in a situation where you are looking for flights of a particular size and are waiting for new offers (because you still have unallocated time on stand for that size), simply knowing how many flights each airline is currently offering doesn’t help (no indication that any are new offers).
I know the new offers might not be for the right size but it would be a lot more convenient to only have to check with those airlines that actually have new offers.
To do that there should be some visual indication as to who is offering those flights.
Could simply use (but doesn’t have to be) the same green circle that is used on the flight planner button on top each logo for any airline that has a new flight offer.
