We were in Alicante, as we live in Spain, and we were getting no help what so ever from the Check-In staff who refused to board us. I decided I would take the chance and fly to the UK where Emirates looked at the same Docs that we presented to Lufthansa and boarded us without any problem. We arrived in Bangkok 4 hours late, but still managed to have a great time.
We had our return flights booked 90days from arrival last December with Lufthansa Group, we were denied boarding even when we showed them the hotel and flight bookings to the Philippines that we were due to take after 57days. So beware, and be lucky!
I should also say, after complaining to Swissair and Lufthansa, they just bounce you back and forth, which is bad considering they are all under the same ownership (Lufthansa Group).
my wife and I had 6 flights booked for the Philippines and a 14nights hotel booking (all paid for) but refused to board us, and to add more insult they cancelled our return flights.
I don't want to panic you but this was my experience, my wife and I arrived at the ALC check-in desk last December and were denied boarding as we didn't have a VISA. I explained that we get 60days on arrival at BKK and were flying to Philippines after 57days (showed them my paid for flights and 2 week long hotel bookings) but they were not having it so we didn't manage to board the plane!!
