Question:
Your airline would like to initiate service between SLC and JFK. The scheduling department has asked you to look at the average scheduled block times (scheduled arrival - scheduled departure) used by existing carriers in the market, JetBlue (B6) and Delta (DL), to determine the optimum block duration as it relates to arrival variance (actual arrival - scheduled arrival), A0 (% of flights arriving on time or early) and A14 (% of flights arriving less than 15 minutes late).
