How will airside transit be provided between T1 and T2?
For example, there are quite a few airlines selling CX tickets for the regional continuation of their longhaul (think LH partnership among them).

If they reopen the quite-recent midfield concourse with its 20 gates, T1 capacity is more than enough for the near future (especially given the airport problem of recruiting staff). Maybe they will first move LCCs to T2 and provide airside bus transfers if needed. But bag transfer is likely to take quite some time.
