Flight times research from internet

For 2 given days in February, I need a list of all flights operated by 10 selected airlines which are longer than 6 hours in duration.

I need to list to include:

1. Flight Number
2. Departure airport
3. Arrival Airport
4. Flights times

The results shoud be presented on a spreadsheet with 4 columns (as per above) and a seprate page for each airline.

This research will be time consuming but simply done using common search engines and Flight Radar website.
