Welcome to the Wefugees Community and I am sorry to hear that you are struggling.
It may occasionally take a few days to receive a response - but we try to give an answer on every question. Sorry that you had to wait a bit now. However, opening three threads with the same content may cause confusion. I hope you don’t mind if I close the two other threads.
Regarding your question: You are right - some airports in Germany provide “facilities” (detention like spaces) for the so-called airport asylum procedure (including Frankfurt and München). At these airports, asylum seekers from “safe countries of origin” and who do no have a (valid) passport will stay at the airport for the whole length of the asylum procedure (which is way faster than the normal asylum procedure - a maximum of 19 days). In case of the asylum rejection, the applicants will be deported right from the airport. Applicants at airports without these “facilities” and in general people who are not from “safe countries” and/or with valid travel documents are eligible for the normal asylum procedure outside of the airport. You will have to formulate your request for asylum towards the police at the airport. In Frankfurt and München are support structures for asylum applicants available- maybe you can share with us the specific airport you need information about.
I hope this answers your question and please don’t hesitate to get back to us (preferably within this thread).
All the best,
