I just saw this question about lost luggage with United. Currently it's only tagged for luggage and air-travel.
I was about to add the "airlines" tag when I thought "Should that tag only be used when comparing airlines or also for specific airlines" which led me to also ponder "why not have tags for various individual airlines" since they will obviously not do everything identically.
I went ahead and created the tag "united-airlines" while we discuss it and VMAtm has changed that to ua since it happens there are also standard codes for airlines much like the standard codes for airports which we are already using. Maybe people will create others, maybe we will delete it. Let's talk about it and see...
Vote this question up/down based on whether you think specific airline tags are a good idea generally, voting here won't cover your preference for full names versus airline codes
