seat map

Hope this has not been asked before,
Having just checked the seat map for my flight next week to check if my requested seats were still there, I found the return map had disappeared, any ideas ...thanks

Can you still view it just not select seats or can you not see it anymore at all?

There is no map at all.

Maybe the Aircraft type has changed

Aircraft change would be my guess too!

Thanks for the replies .I just thought it might be a bit late
to change planes as the return flight is in less than 3 weeks.
But if this is the case how could I Request seats on the new plane as there is no seat map.
Many thanks everyone.

Just a quick update, All my worrying was for nothing, Just returned, we were given our seat selections on both flights in the bubble,did night before check in outbound and ,normal checkin at airport on return.Very happy with all aspects of flights and service.
