From the UK, 26 airports have direct flights to AMS every week.
KLM fly from 16 of these airports.
Given the amount of data for all 26 airports, I thought I'd just post a table that shows LBA in comparison to other airports in England (not including London).
(Happy to post elsewhere the whole breakdown for the UK if anyones interested).
The table below show data for August 2019:

So as you can see from above table, LBA isn't underperforming by any means!
There has been a lot of talk on here regarding why KLM don't upgrade the LBA departures to larger aircraft. Well, for consideration, below is a comparison of weekly departing seats if LBA was upgraded from the current 21x weekly E190, to say 21x B737 departures:
Seats - Aircraft operated
2,100 - 21x E190
2,324 - 14x E190, 7x B737
2,548 - 7x E190, 14x B737
2,772 - 21x B737
Between 21x weekly E190 and 21x weekly B737, there is only an extra 672 departing seats per week, which equates to around 35,000 seats per year. That isn't a huge amount of seats from the airline or airports point of view, and when KLM has so many departure points across Europe, you can understand why LBA might not be the next airport in its network to see an upgrade.
Something else to consider is that KLM will look to upgrade the airports that make them the most money... which will be more likely on routes that have no other competition, NWI and NCL are a good example above.
