baggyred Much depends on your fare class. If a cheaper V/W fare, then you will only have access to the rear of the economy cabin at present - there are some ‘Preferred Seats’ (chargable) but they may be taken if you can’t see them as an option.
The seatmap opens up at T-48, so you ma be able to access the orward exit row/bulkhead seats at that time (for a fee).
