Show Us Your Airmail Covers World Edition

A 1967 cover from Ghana, traditional border with crudely drawn aircraft and Air Mail printed on envelope.

A 1952 KLM first flight cover from Mexico City to Amsterdam with traditional parallelogram border limited to the bottom two-thirds of the envelope.

A KLM first flight from Amsterdam to Santiago, Chile with same parallelogram design as post above, except this has different cachet.

A 1963 commercial airmail cover from a petroleum equipment supplier in Libya with what I call a "partial" airmail designation on the envelope. That is, there is no airmail designation along the edges of the cover, but with just a small area having a design that indicates airmail service, in this case a DC-8 type aircraft and a Via Air Mail.

Philatelic cover with nice airlines etiquette:

I found these in a Tupperware container at a yardsale today.

I just saw this. I hope you don't mind if I jump in with some of my air covers?

And another if I may?

This one I found very interesting, especially the back cancels. Also a nice etiquette is used.

28 April 1937: The first transpacific flight by a commercial passenger airliner is completed when Pan American Airways' Martin M-130, China Clipper, arrived at Hong Kong. The flight had departed San Francisco Bay, California, on 21 April with 7 revenue passengers and then proceeded across the Pacific Ocean by way of Hawaii, Midway Island, Wake Island, Guam, Manila, Macau, and finally Hong Kong.

Oooh thanks perf12, I did not realise this was another clipper cover, I'll add it to my other clipper covers.
I have 2 from New Caledonia I can put up later and a Sunderland first flight too.

Nice Canadian covers Laura2! I especially like the border on the Clipper cover to Hong Kong.

Here is a philatelic cover out of Costa Rica with a Pan Am Airways etiquette and airmail service designation of a single red line trailing a jet aircraft.

Thanks DonSellos I have some others I'd like to put up later.
Nice cover and etiquette you have put up too! Very clean lines.

Here are some Australian air covers
