Hi, my package has been showing 'Flight Departure' or 'Cleared and awaiting international departure' for 6 weeks now. Is it lost and should I call China Post or the seller?

Thank you very much.

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

My Parcel has been stuck on flight departure for days even tho i have received my other parcels that i ordered after this one ? Can someone please tell me what the issue is and why this is taking so long
