Dutch airline KLM has scrapped 22 flights from its early May schedule because it has not yet reached agreement on a new pay and conditions deal with airline unions.

KLM wants to expand its capacity in the summer without taking on extra staff. This will mean cuts in holiday entitlement for staff.

Talks have been going on with the unions since the end of last year without result. KLM says it is now unable to guarantee all the new flights will go ahead, forcing it to cut some planned services.

The cancellations involve flights to Edmonton in Canada, Rio de Janeiro, Bangkok, Nairobi and a number of Chinese destinations.
