I'll be traveling by Lufthansa Airbus A340 - 600 for an 8 hour x 2 journey. What would be the best seats to go for? I'm going to try and get the bulkhead aisle seat or the Emergency exit ones for more leg space. I'm 5'10", even if I wound up getting the normal seats, would there be adequate legspace? Tagging JD666 Also, what would be your suggestion to avoid jet lag? Would you suggest the use of medication? Do I have to lock the check-in bags?
