    /* Mark: If there's one thing you learn from this code, it is this...
   Never, ever fly Air France.  Their customer service is absolutely
   the worst.  I've never heard the words "That's not my problem" as 
   many times as I have from their staff -- It should, without doubt
   be their corporate motto if it isn't already.  Don't bother giving 
   them business because you're just a pain in their side and they
   will be sure to let you know the first time you speak to them.

   If you ever want to make me happy just tell me that you, too, will
   never fly Air France again either (in spite of their excellent
   cuisine). 

   Update by oej: The merger with KLM has transferred this
   behaviour to KLM as well. 
   Don't bother giving them business either...

   Only if you want to travel randomly without luggage, you
   might pick either of them.
