Amsterdam
Looks like some 'not great' news for the new year - Trying to book flights next year and Amsterdam down to 2 daily Mon-Fri in July and August next year and 1 flight from Amsterdam on a Saturday (mid morning flight) and 1 flight to Amsterdam on a Sunday (mid morning flight).. afternoon flight not bookable Mon-Fri.. maybe just a glitch..
I think Newcastle was 5 last summer and is just 4 flights a day next summer..
