I guess that you were right and you do not need to change anything. 220 Mbps is the throughput and not the bandwidth. Assume a scenario wherein you change the destination to Mumbai. Your throughput will get reduced to 110 Mbps (assuming a 20 hour flight), while the bandwidth will stay the same as the networking medium (airline) has not changed, right? Couple of other points - * Two media with same bandwidth can have different throughput depending on the distance (i.e latency) or packet loss or other reasons. Consider two 100 Mbps broadband lines from SFO to London. One goes via the east coast, while other via Asia. Both will have different throughput; difference being roughly proportional to the difference in distances. * 220 Mbps would imply that a maximum of 220 Mb data can pass through the medium, which is not the case, since we are loading TBs of data on the plane. * The window size in case of an airplane would be the size of the data loaded on it i.e the size of the movie collection.
