Spanair lost my luggage too but be honest they stollen my luggage and their strategy is no to answer to any written forms. But finally very good question is about Star Alliance. How Lufthansa main partner of this programmme invited and accepted Spanair to be a member of this alliance. This is Mickey Mouse airline how Verge summarised.
Practically I have few questions:
1. Does Spanair belong to Montreal convention from May 28th, 1999 ? If yes then they have to reimburse 1000SDR in case of not finding lagguge
2. How long Spanair has time to find my lugguage 21 or 30 days before giving him status 'lost'?
3. My national air carrier LOT Polish Airline suggested to be prepared to create civil court action. What do you think about it?
Just I have very simple but practically very hard question to you. Can you try to analyse what did you make/write (special kind of sentences) that finally you got positive result? Any tips will be more than welcome
