According to the EU visa regulation, the valid visa shall in principle be included in the valid passport. If, however, the passenger is unable to obtain a replacement visa in the new passport before travel, he or she may still be accepted on the flight, on the following conditions:

Passengers, who are required to have a visa for their travel to the Schengen area, are now accepted to enter the Schengen area also via Finland with a visa included in an expired, cancelled or fully stamped passport, provided that the visa is still valid, the permitted time of stay has not been exceeded and a valid passport, where entry and departure notes can be registered, is presented at the same time. The new valid passport has to be issued in the same name and by the same country as the passport in which the visa is included.

The new practice is now in line with how other Schengen countries have interpreted the EU regulation.
