Hello,
I hope this message finds you well. I am writing to inquire about the possibility of arranging assistance for my sister and her two young children during their layover at Istanbul Airport. They will be traveling from Munich to Beirut via Turkish Airlines, with a one-hour layover at Istanbul Airport.
Considering that my sister will be carrying a baby bag and two carry-on luggage, it may be challenging for her to navigate through the airport with two young children. Therefore, I kindly request if you could arrange for someone to meet her at the arrival gate in Istanbul and assist her in reaching the transit gate for her onward flight.
I would appreciate it if you could provide information on whether this service is available and, if so, whether it is free of charge or if there is a fee associated with it.
Please find the flight details below for your reference:
Munich to Istanbul - Flight TK1638, scheduled for 09/07/2023 
Istanbul to Beirut - Flight TK824, scheduled for 09/07/2023
Thank you for your attention to this matter, and I look forward to your prompt response.
Best regards
