QR30 from EDI delayed this afternoon (Wednesday) so I've changed my itinerary by 24 hours, now leaving Thursday. I can see my new booking and on my next flight from DOH-BKK (QR834) I've been allocated seat 31J. On most seat maps this is showing as an exit row seat. Is it likely this would have been allocated >24 hours ahead?

I have some doubts as there appears to be a gap at Row 30 too on some sites which looks exit row like. This is on an A330-300 (Type 333H on qrcargo). Can anyone confirm the exit row number?
