For anyone who wants to build their own airline route maps online:
1. Log in to My Maps via your Google account (if you have one)
2. Create a new map and give a title
3. Create several layers on your map for each hub, and rename them by the location of your hubs
4. For each layer:
-Start searching for your hub airport and add its location
-Change "Individual styles" to "Uniform style"
-Add in all destinations by searching their airports
-Lastly, draw lines to represent the routes
*You can color-code each layer for easier reference
This is what I did for LAP Belgian Airlines: https://www.google.c...764788661,0&z=2
Hopefully this helps out. Have fun!
