Tuesday? Sunday? What's the best day?

Those of us who travel frequently often believe that there is day, and maybe a time, when we’ll find the best deals on airline tickets.    What airline, website, day, time in advance of the trip is best? Advice I’ve received from many a frequent traveler?  Book on Tuesday, after 3:30 pm eastern time.  

But this week the Wall Street Journal published an article telling us that Sunday’s the day.  http://online.wsj.com/articles/the-best-day-to-buy-airline-tickets-1413999377

Read through Scott McCartney’s article and you’ll discover that airlines realized that, especially for leisure travel, many of us do our searching on the weekends.  That what hadn’t sold during the week might be purchased by the casual visitor on a Sunday afternoon.

But those of you who are Tuesday believers, don’t lose hope.  It turns out that Tuesday can be a good time to find that special offer.  An extra discount on the flight you want.

So now it appears there are two days to check those prices.  But whichever day is yours, remember sooner is better than later.  In his study it showed that domestic (US) flights had the best prices 57 days in advance while international flights from the US were best at 10 months in advance.

Now my question is do I book my February Nashville flight today, Sunday, or do I hope for better luck on Tuesday afternoon?
