I've had a read of the FAQ's etc. and done a search, but could somebody confirm if I can change the first two segments of a DONE5. It is out of Sweden on an AA paper ticket (20 segments). My flights currently are ARN-MAD-EZE and I'm looking to change to ARN-LHR-EZE.

I've read a recentish post that says you can, but some older posts seem to say only if your ticket is from N/S America.

Thank you,

chris.
