Ask HN: How can airports wifi know my flight number?
Hello,
I'm here at heathrow-airport and the wifi login knows my flight number is advance? How is this possible? I cleared the cookie from my british-airways checkin session, but the wifi-system still guess the correct flight?
edit: Worth to notice is that I have made two connecting flights from heathrow during the last two days, and the wifi-login displayed the correct flight number both times. The flightnumber field is even disabled, you can't change it...
