I read Starlink is coming, not sure if the source is reliable.

Also, why does the retrofitting take so long? With the current figures of approximately 150 aircraft still to go and an average time of 37,5 days per aircraft which makes them roll out 20 updated cabins per year. It will take them another 8 years to complete the retrofit. With them upgrading newer aircraft before older ones it seems like these older aircraft would have been taken out of the fleet already anyway right?

Using the sheet as a source. Thanks for sharing btw.
