I've noticed that for some time, the "VIA" airports are missing in the info box to the left if you click on an airplane. If you select the flightnumber, the "VIA" airport is still showing up, i.e. http://www.flightradar24.com/data/flights/ba3579
Would be nice to see the "VIA" airports again in the box to the left, so it isn't misinterpreted as a diversion
