It's your best chance of not having your kid taken from you. Use whatever excuse you have to... You only feel comfortable flying southwest but you can't get through to the ticketing agent. You have covid and can't fly. Then you got the flu. Then you got RSV. Then you got covid again. Talk to a lawyer, the consulate whoever but stay where you can sleep indoors.
