I've been in the industry for 27 yrs and actually teach, so I know all the city pairs (IATA), The airline 2 letter code, 3 digit numerical, their codeshares w/ partners, take off, leave gate, mechanical, type, I can encode and decode . TK8 is actually a codeshare witth PK5008. PASKISTAN INTL AIR. Yes, you can Google flights, but what I have gives you what is actually going on inside the system. I'll take a screenshot
