While I found that the lines for economy check-in are often super long, the only time I have had issues was a Saturday night departure where the flight was oversold in Y.

My main observation is that things actually calm down a bit once you get into the check-in hall. The scrum outside the entrance in combination with the (ONLY) two baggage scanners will eat into your schedule.

Just remember that the CX check-in is at the left end of the desks so you avoid the masses using Air Lanka and Emirates.

Arrivals is pleasant compared to 6 or 7 years ago.

Happy wandering
