Hi, I want to know how long it will take to see the package in my country (Poland). I can see the status „International flight has departed” and that’s it, I’ve seen this for 3 days, no further update. Is the plane lost or what?

YunTrack number: YT2320621272271416

Hello, Tracking number LZ204298090CN my Package has been since 2 days in flight when will it arrive

I had a package sent to me on April 14th, through China EMS. It was collected on the 15th and despatched to the UK on the 17th, however the tracking site I was provided with and my local couriers tracking both have no updated since. I thought EMS was usually quicker than this and I looked it up to read that EMS from China to the UK usually takes 7-20 days, but my tracking has not updated in a month.
I found tracking websites that share more detailed information however this is what I get:
May 8, 2021 22:14 -Flight Departure
May 8, 2021 22:14 - Transiting via the transit Airport
May 9, 2021 21:10 - Flight Departure
May 10, 2021 12:02 - Flight Departure
May 12, 2021 15:16 - Flight Departure
May 13, 2021 00:07 - Flight Departure
May 14, 2021 09:00 - Flight Departure
May 15, 2021 09:44 - Flight Departure

Why has its flight departed so many times? What does this mean. Should I be concerned about my parcel yet?? Or is taking this long normal for EMS
