Need to book the wife, infant and I tickets to WAW from LHR on the 25th December. However i need to come back earlier (29th) while they come back on the 4th Jan.
Is it possible to have this under one ticket rather than booking myself separately.

Under one booking helps on quite a few things, mainly as we have a voucher what only works on one booking as a family. If we split the booking the voucher will only work on one booking. The other is that the wife is silver (i dropped to bronze this month) so pre booking seats would be super advantageous.

Guessing this cant be done online, though can this request be done via the new bookings call centre? Or is their any other advice from you fellow FT'ers...

Wanted to see what my options were before braving the queue to the call centre.

As always appreciate the help in advance.
