Mailed in 2011 with three different stamps and most of the postmark.  Some of the typical USPS postal abrasion on the reverse.  Grade: 3

Card of a Boeing 737-800, and the caption has technical details.  The registration number, D-ABKC, confuses airfleets dot net, and confuses us too.  It may be that this aircraft is now with the Romanian airline Tarom.  Or maybe not.  Go see.  Three of these cards are available.  Two were mailed in 2011: one has two German stamps and partial postmark (Grade: 2, $5) and the other has three different stamps from Austria, also partial but illegible postmark (Grade: 3, $5).  The third was mailed in 2013, with stamp, postmark, and Priority label (Grade: 1, $5).

Absolutely the perfect card for those of you specialising in aviation.  Mailed in 2011, with stamp, full postmark, blue bilingual Mit Luftpost sticker … wonderful.  To be honest, we don’t mind not selling this, unless you really want to own it.  Grade: 1

Not postally used, but with a brief inked message on the reverse.  Grade: 3

Unused, 4-1/2″ x 6-1/2″ postcard.  This is a very, very good airport.  Grade: 1

It helps to know the context.  Ngong Ping 360 is a complex containing a large seated outdoor Buddha, and one way to reach it is by these cable cars that have an annoying habit of stopping mid-ride while they sort out technical problems.  But they get a spectacular airport view while they wait.  Unused card measures 5-1/8″ x 7″.  Grade: 1

Three of these unused 5-1/2″ x 7″ cards are available.  Grades: 1

To be specific, registration number JA 8984 is a Boeing 777-246, and delivered to JAL in April, 1997.  The card, though, was mailed from Japan in 2011 with a nice airplane stamp, and postmark.  Grade: 1

Unused Photo Fabrique card.  Grade: 2

It’s not really cheating to put this cover of a 1938 book by the famous aviator Anthony Fokker (but, yes, this is a postcard) into the “Airlines/Airports” category.  Mailed from Ireland in 2011, three stamps, bilingual Aerphost sticker, and full postmark.  Grade: 2

One of our favourite cards ever, and even with it right here next to us as we type this text, it is hard not to look at the facial expressions on the attendant and the little girl.  The sender’s message (from Finland) is really the icing on the cake for this one.  Mailed in 2011 with stamp and postmark and blue Priority label affixed.  Grade: 1

This 3-7/8″ x 7-7/8″ card has four stamps, partly legible postmark, and blue bilingual Prioritaire label affixed.  Grade: 1

Though the airport closed in 1998, the card was mailed in 2011 with six stamps and three full (and specially hand-stamped) General Post Office postmarks.  Grade: 1

Great vintage card, “of an era”.  Mailed from USA in 2012 with four different stamps, and USPS postal barcoding, but no postmark so the stamps are uncancelled .. Grade: 4

For several years now, this has primarily been a domestic or military airport.  Two of these cards are available.  They date from 2009, and are from the “Airports of Thailand” public company.  They measure 4-3/4″ x 6-1/2″.  And while they are clear and crisp on the front, they are very dirty on the reverse.  Just so you know!  Grades: 4

The card was mailed from Portugal in 2012 with stamp but no postmark.  The aircraft is still active, first flight in November 1997 for TAP Air Portugal.  Quite straightforward, this one.  Because there’s no postmark, Grade: 4

Unused card issued by the National Museum of Science and Technology in Ottawa.  Grade: 1

The card was mailed from Finland (not Germany) in 2011 or 2012, with stamp and Priority label and some extra stickers.  The caption gives detailed aircraft information, and if we can possibly read the registration number as D-AIAA, the first flight date was November 1975 but in the late 1980s it went to Air Inter where it was subsequently scrapped, the registration number having been changed to F-BUAM.  So there.  Grade: 4

Printed in Finland, and mailed from there, with stickers and so on, this is about as generic as a card can get and it is hard to understand the appeal.  But here it is.  Grade: 4
