2x year I transit AUH from BRU to BKK, have 1h40min.
2h25min in the other direction, a bit too long.
Never missed a connection, although sometimes no more than 30 minutes in the lounge.
And around midnight the lounge can be crowded, nice food and drinks available.
It can be a long walk from gate to transit area, security check and lounge.
Sometimes we disembark in the old terminal, it is a 5 minutes walk then to the new terminal.
