Greetings. I am sorry to hear about how far your children are. There may be some inexpensive flights from Tennessee to your area.
You can ask that the court impose on her the duty to meet you half-way (either on costs of transportation if you choose airfare or by having the children appear half-way between your home and theirs). I doubt that the judge will impose that only a blood relative can bring the children, as the case is between you and her. If she wants to hire someone or send the children on public transportation, she may be allowed (depending on the age of the children). Best of luck.
