Just booked my parents in LH F in next week. We (3 generations) are all booked FRA-PHL, 4 in C, 2 (parents) in F. What are the chances we are allowed in under the "all children" of the ticket holders?
Parents are 66, us 39, kids 16/4. (We have had both kids to the FCT past 3 years-and they will miss it if "nana/pappy" get in and they dont!

)
Thoughts???
PS-I keep looking for F availability...seatmap (i KNOW its not a great indicator) just shows 2 booked seats on 340-600.
