Just checked two people (on the same reservation) in using Tigers new web-checkin, and the seat allocation system has sat them apart from each other. The flight is not till Monday so there are obviously free seats together, but their computer system isn't that smart! After checking in, you cannot make any further changes so you are stuck with these seats.
So in conclusion:
If you want to sit next to your partner on a flight you will now need to pay! Either $8 per person to allocate seats next to each other when booking, or $10 per person to ignore web checkin and check in at the counter, or $20 per person to include luggage and check in at the counter.
I still love Tiger though. Couldn't afford to fly at all if it wasn't for them!
