Pro Tips

Get help faster

Have your booking reference ready

Airlines can resolve issues far faster when you start the call with your PNR or booking confirmation number.

Call during off-peak hours

Early morning (before 8 am) or late evening calls typically have the shortest wait times across all carriers.

Check the airline's app first

Many changes — seat selection, check-in, minor rebooking — can be done in-app without holding for an agent.

Know your passenger rights

Under DOT rules, airlines must offer refunds for cancellations and significant schedule changes. Reference this when calling.

FAQ

Common questions

Which US airline has the best customer service?+

Alaska Airlines and Delta Air Lines consistently rank highest in J.D. Power's US airline satisfaction studies. Both offer 24/7 phone support and proactive rebooking during disruptions.

Can I change or cancel my flight over the phone?+

Yes. All major US airlines accept changes and cancellations via their customer service lines. Have your booking reference and passenger details ready before calling.

What is the best time to call an airline?+

Typically early morning (6–8 am local time) or mid-week (Tuesday/Wednesday) have the shortest hold times. Avoid calling on Mondays or during weather events.

Do airlines charge a fee for calling to book?+

Some legacy carriers charge a small phone booking fee (usually $15–$25). Budget airlines like Spirit and Frontier more commonly apply this fee. Check directly before booking by phone.

What if my airline has been acquired or rebranded?+

If your airline has merged (e.g., Virgin America into Alaska), contact the acquiring carrier using the number listed above. Your original booking reference will typically still be valid.
