I did not fly LO out of AMS since before the summer, so I didn’t know that they either prolonged this or made it permanent. At least AMS wise.

LO fares ex AMS are usually quite high. Not sure if it’s because they use Embraers for AMS or they use Embraers because bookings are low because of the prices.
