The boarding process is still chaotic and unorganized. I love the “lines” in the Atlanta airport with the different boarding levels. Makes everything more organized. For a long flight, over 4 hours, more refreshments could have been added. There should be an enforced limit on how much carry on luggage a passenger can take.

That’s why a Seattle/Tacoma Intl Airport to Brussels Bruxelles-National Airport flight would often be abbreviated as a SEA to BRU flight. This flight route has multiple associated airports, so we think it might be helpful to learn the name and codes of them as well. They are Charleroi Brussels Airport (CRL), Antwerp Deurne Airport (ANR), Ostende-Bruges Airport (OST), Liège Bierset Airport (LGG).
