My last hurrah redemption - booked back in April - is meant to start this Thursday. For my sins I've not been checking things (CMT, FT, etc) regularly, only tonight thinking to go take a look. I am supposed to be flying BRU-ADD-ZNZ and ZNZ-ADD-FRA-LHR, with ET and LH (last 2 legs).

Both bookings now just throw an error on checkmytrip.com.

Both bookings appear under "my bookings" on flybmi.com, albeit with the dates they were originally made (I brought them forward). I can add my API to one booking but get an error when I try the other.

Both bookings can be looked up on ba.com, but the "print e-ticket" link says they are paper tickets

Needless to say I don't have paper tickets. I saw this recent thread which mentions "certain airlines". Is ET one of them? I have a positioning flight to BRU and hotel booked in Zanzibar (which it's now too late to cancel). Are my flights safe? Do I need to find an ET office/desk? All advice gratefully received. I'm in a bit of a panic here
