My parcel to Spain, sensed via SAL, has been waiting for flight since April 16th, usually it only takes a few days on doing this, but it hasn't updated for more than 40 days. Why can this be happening? Is my parcel lost?

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

Please check these parcels and Please export to air flight quickly following number of parcels.
