Is there any means for airlines to access a person's flight itinerary?
For instance:
Can airline "A" access all of John's flights in the past and in any flight he has booked in the future with Airlines "B".
Would this change if Airlines "B" and Airlines "A" have a partnership/codeshare agreement?
Addendum:
I have an interview with Airline "A" located in their home hub in Europe, which is about a 25-hour flight to get there from NZ. I got the invitation Sunday night, to come by not the next day, but the Monday after. It's impossible for me to request a leave on such short notice. Also tickets are hard and expensive to find due to multiple connections.
I was contemplating on saying that I'm on an overseas business trip currently, and I'll be coming back on XX/03/2018 and we can do the interview then.
Addendum for "put on hold as unclear what you're asking by George Y., Ali Awan, Giorgio, Rory Alsop, CGCampbell ":
It's a simple question:
Can an airline look at an individuals past present and future itinerary by it's own means?
