I have booked return flights with Emirates from Manchester to Kathmandu (with a connection in Dubai) for Apr/May 2020. So it looks like Manchester > Dubai, Dubai > Kathmandu and then Kathmandu > Dubai, Dubai > Manchester.
I recently revisited the Emirates website to update some of my details and went to manage the booking. My eTicket contains details for the original flights I booked, there and back. However, when I visit the 'seat selection' page, there appears to be an additional flight going from Dubai to Kathmandu. So I'm now seeing Manchester > Dubai, Dubai > Kathmandu (which is all fine) and then Kathmandu > Dubai, Kathmandu > Dubai, Dubai > Manchester. Why are there now two Kathmandu > Dubai flights? The additional flight is the same day but is some eight hours earlier at a time that won't work for me.
My friend who has booked onto the same return flight has experienced the same.
