Best Times to Call Airlines (Lowest Wait Times)
Early Morning: 5 AM – 8 AM
This is consistently the best window across all airlines. Call volumes are lowest and you’ll typically connect within 5-10 minutes even during busy travel seasons.
Late Night: 10 PM – Midnight
The second-best window. Most travelers are asleep, so call volumes drop significantly.
Mid-Week: Tuesday, Wednesday, Thursday
Avoid Mondays (post-weekend surge) and Fridays (pre-weekend rush). Mid-week calls connect faster on average.
Worst Times to Call Airlines
- Monday mornings: Highest call volume of the week
- Friday afternoons: Pre-weekend travel rush
- Day before major holidays: Extremely high volume
- During weather events: Lines flood instantly during storms
How to Get Through Faster
- Use the callback option — Most airlines offer automated callbacks. Accept it — you keep your place in queue without staying on hold.
- Say “agent” or press 0 — Skip the automated menu to reach a human faster.
- Use elite status — Frequent flyer elite members are routed to priority queues with shorter wait times.
- Try the airline app first — Many issues are faster to resolve through the app than by phone.
What to Have Ready Before You Call
