Airside Xstore Transactions - validating flight numbers and destination tax

We are using Xstore 21.0.3 and planning to implement airside store transactions for our Heathrow store location.

I am reading from xstoresuite-2103-catg.pdf to understand more about it, but have the following questions:

(1) When the boarding pass is scanned by scanner, Xstore validates the flight information. There is a table called com_flight_info table. Are we supposed to build an integration to get the latest flight details from Heathrow DCS?

(2) Where can we get data for the tables com_airport, com_airport_zone, com_airport_zone_detail?
