Re: Transavia to serve again BRU-INN between December '20 & April '21

That’s great news. There are some flight already listed at the winter schedule 20/21 on INNs homepage, but I’m not sure if all routes are really going to happen. The Netherlands and GB would be very important for the winter tourism, but this is only going to happen if COVID cases go down in all coun...

Re: Few questions about the A310 (and A300)

If you look at aircraft more or less contemporary to the A330, like the Tristar and the DC-10, they don't have large fairings either. Actually, the DC-10 does have a quite large fairing underneath and behind the wing, which even got extended as far as half way on top of the cargo door. But yes, the...

Handle on side of overhead bins

Maybe I just never noticed before, but on my last flight on a FR 738 I saw this for the first time. Before the flight attendants closed the overhead bins, they pulled or pushed a small handle on the side of the bin. I attached a picture of it, the handle is in the red circle.
