I did an exercise during the last week whereby I noted all TCX and VS long-haul movements so I could better grasp their schedules and the TCX one threw up a couple of questions.
1. How come there is different flight numbers for some routes despite departure time being at the same time. For example TCX2924 to LAS leaves at 9.15 on Tues and Sat, and TCX 2640 leaves at the same time to LAS on a Sun. Why not keep the same flight number?. (there is also 3 different flight numbers for JFK, 2852 Mon, Weds, Fri, 2848 Tues, Thurs, Sat and 2866 on Sun)
2. Also how come the same flight number does flights to the same destination at different times during different days. For example TCX2604 does MCO at 11.00 on Mon however on Weds and Fri it leaves at 12.00.
Also a question from the VS schedule:
ATL has been A333 for the last few weeks. It goes back to A332 next week, is this due to the 4th A332 being ready for service or are we taking back one from LGW?.
If anyone would like the spreadsheet don't hesitate to message me.
