IATA code and continent

Hi, I saw this edit made by you and I undid it, as Milano Porta Garibaldi railway station (Q801187) is not an airport and IPR is not a IATA code. I also noticed that you added the wrong "Antarctica" :) Have a nice day, --★ → Airon 90 16:01, 4 April 2020 (UTC)

Thanks for your follow up!

Note that IATA codes are assigned to many other transport-/travel-related points of reference (POR) than just airports. This has been discussed and explained extensively in discussion about IATA Location Identifiers (LI) on the IATA airport code property talk page. In particular, IATA officially assigns the IPR code to Milano Porta Garibaldi railway station. On their public search page, IATA indeed only disclose airports. However, their paying release (named CWD) include all the types (more specifically, heliports, maritime/river ports, railway stations, bus stations, and cities/metropolitan areas). A proxy for all those reference POR is available on OPTD GitHub. Those IATA codes are public, indeed because they are used by transport/travel providers for travellers to book their trips.

You can see a proxy for all the possible trips also in OPTD GitHub. See for instance lines ##6212-6216, where you can read that Trenitalia (IATA code: 7T; yes, train companies also have IATA codes) has trips (trains) departing from IPR to IMR (Milano Rogoredo railway station), ITT (Torino Porta Susa railway station) and TPY (Torino Porta Nuova railway station).

Do not hesitate to send me a private message if you would like more details or are keen to contribute to those projects.

I therefore intend to re-add all those IATA codes for those railway stations, as they are indeed used by actual booking systems, and Trenitalia is not the least known train operator.

Thanks for your correction on Antarctica! -- Denis.arnaud (talk) 18:36, 4 April 2020 (UTC)
