Answer: random sampling

Step-by-step explanation:

In statistics, a random sample refers to a subset of the population surveyed by the researcher, selected in a way such that all the individuals in the population has an equal probability to get selected.

Given : To determine customer opinion of their check dash in service , American Airlines randomly selects 70 flights during a certain week and surveys all passengers on the flights.

Here probability for each flight to get selected is equal.

Therefore, a random sampling is used here.
