If I have a record locator (PNR?) the 6-character code that passengers get, how can I get the details of the corresponding itinerary? Is there some (possibly paid) service on the web that can do this?
It is quite easy to look up information about a reservation if you have the PNR (a.k.a. record locator, booking reference, confirmation code, reservation number, etc.) or ticket number plus the name of the passenger. Most major airlines provide an online form where you can do this, e.g. ANA, Icelandair, Air Canada. The only catch is that you must use a locator which the airline's system understands, which you may not be in possession of if you booked, for example, through a partner airline.
Depending on where the ticket was booked, it may also be possible to look up the information from a GDS or travel agent website. Expedia lets you look up an itinerary with the itinerary number and the email address associated with the reservation. For Travelport there is ViewTrip, which lets you do a look up with a last name.
I sure hope there would not be any, and, as "the bad guys" presumably already would know,for reference:
I believe that exposing possible issues, [i.e. in this case big thanks to pcmag] and me just trying to help to spread out the messgae, may speed up to get fixes done, and, to repeat, the bad guys already presumably know.
So, there is nothing you can do about the tags attached to your luggage between the luggage drop and the arrival belt, but, better remove them after the belt [ BUT KEEP ALSO THE LUGAGGE TAGS AVAILABLE until you are out of the airport, since you may need them when passing the customs and/or exiting the airport, as in some places, even on domestic flights, they cross-check your luggage tag and the "copy" you have to avoid luggage thefts. Also, consider where you throw away your "boarding passes" or other documents where traceable information is included. It is not only about your itinerary, but you might risk also more personal information revealed!
