I haven't seen this discussed or mentioned here yet, so thought I would post it, even though it is a month old.
SITA in early November announced that a new standard in airline domains would be implemented as signed off by the IATA airlines at a conference in October.
The standard is basically that the IATA airlines will implement their 2 letter IATA designator as their website address. Some airlines are also expected to change their email system from their current to the new SITA standard.
3 airlines have so far signed up for this initiative:
SITA says this will be especially handy for frequent travellers who already know the 2 letter/number identifiers for their airline.
I would expect that most airlines would sign up for this new initiative, but I wouldn't expect their email systems to change much. The airlines, when dealing with the public would want to keep their "brand" in their email, but this will be especially attractive when it comes to communication between airlines, especially if they keep the Type B standard (as SITA has suggested) for the .aero domain.
I also wouldn't expect the airlines to get rid of their current domains altogether. Most of the are "brands" in themselves, and there is a danger for the airlines if they were to be forced to adopt this initiative, e.g. all airlines change over to this new system, along comes Joe Public who doesn't know the first thing about the airline industry. He lives in Dallas and wants to fly to Mexico on American Airlines. Not knowing the 2 letter designator for American, he puts www.am.aero into his browser, and gets taken to the Aeromexico site, and it results in a lost sale to American.
I know this is probably as dull as dishwater to most of you, but for those of us who have dealt with SITA products in the past, this is surely another step in the right direction for the group in streamlining their airline communications.
