Unless you have someone handling you, check to see where you are in the lifting order for the next attempt because it changes each time based on what weights are selected (always in order from lightest to heaviest). You don’t want surprises at a meet, and you don’t want to suddenly find out that you’re the next one up when you weren’t expecting it, you want to be mentally prepared.
The number of flights is irrelevant, what matters is how many lifters in each flight because the first flight will go through all their attempts for a particular lift before the next flight is up. It usually takes about 1-2 minutes on average per attempt, depending on how fast they load the weights and if the lifters go straight to the bar when their name is called or they screw around a bit. Deadlifts go faster because there is no rack to adjust. If there are more flights then the whole meet will take longer and you will have more time between each lift (as in squat, bench, deadlift).
Maybe get used to longer breaks between heavy lifts in training if you feel that this is an issue.
