United Airlines flyers will need to check in at least 45 minutes before departure.
The new rule, which takes effect June 3, applies to both customers who are not checking a bag and customers who are checking one.
⏰ Previously, flyers who weren't checking a bag could check in as late as 30 minutes before departure.
What they're saying: A United spokesperson told AP the change "brings greater consistency for our customers" and brings the airline into line with many of its competitors.
