It is a family travel from HK to Munich on Jun 29. Lufthansa changed my seat reservation I made in Jan(6 mths before) WITHOUT NOTICE and break my family of 3 seating separately. I noticed that only because I checked my booking online again 4 days before departure. I called and they said the one I reserved before is a special row(but not an exit row, it’s just the 2nd last row, row 57) and they said once there is an unaccompanied child they have to take that. But when I made the reservation there is NO SUCH WARNING and they cannot arrange sitting together again because the flight is very full. I asked them “are you going to place a 4 yr old kid sitting with strangers and leaving her to cry throughout the trip”. The customer service admits the system is bad and said they will “try” to request but no guarantee. I called the HK office and they said that they will release 2 rows that are blocked and call me the day before departure to confirm the seats. They admitted the arrangement is bad and suggested me to make a complaint. I am thinking if I did not pro-actively check the booking again and wait until I checked in, it means that we have to sit separately and in particular, my 4 yr old kid has to sit by herself and losing the care of her parents for a long flight even their parents did reserve the seats to sit together well in advance. I booked Lufthansa only because they allow seat reservation during my online booking so that I can guarantee the whole family sitting together. But it is clear that such seat reservation is not delivered. I left the message on facebook of Lufthansa and Star Alliance and only receive the feedback from Star Alliance. Lufthansa is forced to follow up with me after Star Alliance alerted them. The conclusion is that the whole Lufthansa care less their customers, care less family travel with young children as they dare to change your seat reservation without notice and arrange a 4 year old kid to sit by herself with strangers for long haul. I told my friends and colleagues who are frequent travelers and they were all speechless. The conclusion is NEVER LUFTHANSA.
