IS SUNDAY STILL THE BEST DAY OF THE WEEK TO BOOK A DOMESTIC AIRLINE TICKET TO SECURE THE BEST FARE?

Q—I have a guidebook that says Sunday is the best day of the week to book a flight within the USA. Prices seem to go up on Monday. This sort of makes sense but it also seems too simple to be true.

Is there a time of day when the average air ticket is lower? We are now at the point where we will be doing more domestic travel to visit kids and grandkids and I am trying to figure out a simple strategy. Thanks very much.

A – Airline strategies are fun to write about but much of what is written is old by the time it reaches print. You want to book domestic flights between 30-60 days before departure. But there is no one day when rates are lower. The new breed of computer algorithms is changing fares constantly based on availability and sales data streaming in by the millions. There is no way a human can try to predict or even keep up with those changes.

Wednesday and Thursday may be the best days but that is really hard to certify. We do know that flights that leave between 6:00 and 8:00 am and flights that depart in the evening between 10 PM-1:00 AM tend to have better pricing and better on-time records than mid-day departures.
