Hello. I just booked the first part of my trip in october from YUL to MXP with Delta. I need now to book the return (MXP-YUL or MUC-YUL). what are your comments about each choice ? Choice between TK or Lufthansa. Business class. TK is cheaper but, with the last days events, is it a too risky choice ? Lufthansa is better but, is it Worth (business class - MUC or FRA to YUL).

ps: its 52000 points each seat. anybody can let me know if there is some open seats on october 14th-2016 ? I have to move points from SPG to miles and more OR Aeroplan. Can I put on hold the awards with Lufthansa ?
