A general question about alliances:

We want to add an alliance filter to our routemap FlightConnections.com
The idea:@:-) When you select for example 'Star Alliance', you will only see airports and flights of this alliance.

Some airlines codeshare with airlines wich are not in the same -selected- alliance.

Should we also show these codeshare flights operated by non-members?
Are these flights part of selected alliance-network?
