Not one of his best efforts, it seems to me.

The flights of associated companies being shown in black are much more prominent in the diagram than those of Imperial Airways, shown in a
rather weedy reddish. Or perhaps they just faded?

Then the daily flights between, I assume, important routes are shown in a rather inconspicuous way with dashed lines, whereas the less frequent
routes have solid colour. It's impossible to guess, without looking at the key, which routes have the greater frequencies. I'd have thought
it would be a rather basic precept of graphic design to have prominence of the line proportion to service frequency, or at least proportional
to something useful. And the representations of summer-only and winter-only seem to have no connection to each other.

Maybe this was a draft and he did a better one later?

Here's his early draft of the London map:

I'd expect them to exist in various degrees of hand-drawn sophistication
before being productionised by an artist rather than a designer.

Perhaps recliner can tell us if this map was ever a public document
circulated by the airline.
