It's a tough game when guessing is the basis of decisions but perhaps DL should've started recalling a bit sooner:
“Deja Vu for the 3rd time: Delta Air Lines has cancelled nearly 100 flights this Easter weekend as the airline continues facing pilot staffing challenges. Additionally, we’ve seen a large amount of flights being severely delayed as well this weekend.”
“It’s very disappointing to see this, as this is the 3rd major holiday weekend in the past 6 months that Delta has had to cancel tons of flights due to pilot staffing issues.”
