I am planning to meet Mrs Antonina Kobeleva (Ukrainian refugee, program U4U), 87 y.o. with limited mobility, arriving at JFK on Jan.12 2023 by flight TK1 (Turkish Airlines from IST).
She doesn't speak English and will be overwhelmed after the long trip. I've ordered a wheelchair and received confirmation from Turkish Airlines about the wheelchair assistance in IST.

My question:
Could you provide a wheelchair with a Russian/Ukrainian-speaking assistant who could help her:
1. Move from the plane to pick up 1 bag (luggage) and
2. Move her via the passport/immigration service office and
3. Bring her to the Arrival exit of Terminal 1 where members of our Ukrainian community and I will be waiting for her.

Please let me know if you can do it and how much it will cost
