My friend is flying here with his wife and kid from Germany. Their trip is about 37 days but they are flying to Bali for a few days anyway so they don't need to worry about a visa.
Their return flight is booked from Germany but the Bali flights aren't booked yet. Will the airline give them any issues for having an over 30 day itinerary? Note they haven't been to Thailand in almost a year.
Thanks
