Quick Answer
Summer is peak UM travel season. Book 4-6 weeks ahead, choose morning flights, and have backup plans. UM fees don't increase in summer, but flights fill up fast.
Why Summer Is Peak UM Season
- Custody exchanges: Kids spending summer with the other parent
- Grandparent visits: Extended time with family
- Summer camps: Flying to specialty camps
- Family reunions: Meeting relatives in other states
Airlines see 3-4x more UM bookings June-August compared to winter.
Book Early (4-6 Weeks Ahead)
⚠️ UM Seats Are Limited
Airlines cap how many UMs can be on each flight (typically 3-5). Popular routes sell out UM slots even when regular seats are available.
Don't wait until the week before. Book at least 4 weeks ahead for summer travel, 6+ weeks for peak dates like:
- Memorial Day weekend
- July 4th week
- Labor Day weekend
- First week of August
Choose Morning Flights
Morning flights (before 11am departure) are best for UMs:
- Fewer delays: Weather issues build through the day
- Recovery options: If cancelled, afternoon alternatives exist
- Kids are alert: Better behavior and attention
- No redeye risk: Most airlines ban UM redeyes anyway
Have Backup Plans
Summer thunderstorms cause delays. Be prepared:
- Know alternatives: If on Southwest, know the next nonstop time
- Both adults available: Drop-off and pickup adults should have flexible schedules
- Pack for delays: Snacks, charger, entertainment for long waits
- Airline app: Download the airline's app for real-time updates
