I would like to ask my ID card expired on October 30, I want to go home by plane in February 2019, can I buy a ticket?

Tickets can be bought. You can go to the local public security bureau to apply for a replacement ID card in another place or go to the airport to register for a zero-hour ID card. safe journey

No, the ticket is 60 days in advance

Proof of identity can be obtained at the airport.

Yes, the ID number is unique and never expires. The ID card that has just expired can still be used normally, even if you are blocked or you don’t have an ID card, you can still take the plane. Just arrive at the airport a little earlier before arriving at the airport normally in advance, and go to the airport police office (or airport police station and other similar institutions) to issue a "temporary identity certificate", which is the regular business of the airport police. After issuing the certificate, you can go through all the formalities for boarding the plane. Due to the large business volume of such businesses in big cities, airports in big cities like Beijing and Shanghai have already used face recognition technology to use machines to issue certificates by themselves.
