4th and final Edit as of 18MAY11 1500PDT.
As of 1500PDT on 18MAY11, UNITED has removed flight number UA093 and UA175 as codeshare flights operated by Continental (See below for latest screenshot). However, on timetable search, these flights are still appearing for the time being, which will be removed eventually.

The Star Alliance member responded that these flight numbers were loaded due to system glitch. It appears that these flight numbers were load during the weekend of 13MAY11.

Traditionally, airlines retire a flight number after major crash involved in full loss of passengers and aircraft, including AIRFRANCE AF447 (2009) or Korean Air KE007 (1983). However, some carriers re-use the retired flight numbers when needed. In addition, there were no specific intention/motivation to highlight this. The only “intention” was simply pointing out the fact that these flight numbers are re-appearing.

3rd Edit as of 18MAY11 1100PDT.
On 18MAY11, UNITED launched its new twitter account, and responded to several twitter users that the airline is removing planned reinstatement of UA093 and UA175, few hours after this post appears. According to media reports, these flights will be permanently retired.

However, as of 1100PDT, these flights are still available for reservation (latest screenshot of flight status and flight availability as of 18MAY11 is attached in this post, see below). These flight numbers may be removed as early as today, or Saturday 21MAY11 at the latest, the day when US carriers updates most of their flight information and operation changes. (Routine change occurs on Saturdays)

Below is the original article appeared on 17MAY11, including screenshot of the UA system display (through Sabre reservation system) of these flights.

2nd Update at 17MAY11 1545PDT. Original update: 17MAY11 1535PDT.

As part of its flight numbers re-alignment, including flights operated by Continental Mainline, UNITED starting 21MAY11 will be re-activating flight number UA093 and UA175, which was retired nearly-10 years ago, immediately after the US Terror Attacks on Sept 11, 2001.

These flight numbers will be used as a codeshare flight, which Continental is the actual operator and inflight service provider. The UA-coded flight will be displayed on airline and travel websites for reservation, flight status updates, as well as airport check-in counters, departure/arrival monitor boards and the gates. Under Government Regulations, these codeshare flight numbers are required to appear along with the actual operator of the service.

A list of Continental Mainline operating flights, carrying UNITED flight number range UA001 – 199 for the first time starting 21MAY11, can be found here.

    Gotta agree with Jeremy…this number will forever be embedded in the minds of anyone who was touched by the horrible events of that day. 93 and 175 may just be numbers, but with the word “United” in front of them, they take on a whole different meaning.

    This doesn’t seem right. Those flight numbers, as well as the American one’s should never, ever be used again.

    United has acknowledged that this is an error and the flight numbers will remain retired.

    Jeremy,,, It’s just a flight number. Calm down and return to your ratty recliner.
