I know people who have taken this flight and hated it. It is very uncomfortable for a 6-7 hour flight.
I don’t know if they have now got new aircraft that is more comfortable for the long-haul for this route. Earlier with all the engine issues and groundings that 6E was facing they were flying painfully extremely uncomfortable aircraft on this route. Moreover, they had packed the cabin so densely that they had I think reduced the number off toilets on board. Not the most comfortable situation.
