KLM Amsterdam
Noticed in other threads comments that KLM had reduced some freqs at certain UK airports.
S17 here had 4 return flights M-F with temporarily a 5th reinstated for part of the summer.
S18 looks like 4 return flights as far as I can tell, no signs of a 5th this year so far, unless I've missed it.
Here's hoping for continued growth in 2018, continuing the recovery that took root in 2017. But economic factors - and Brexit - may have a say.
ps. Interesting BA have a full programme f/t LHR today - I recall the days the airport was shut on NYD!
