Auto insurance is obviously different depending on the type of coverage you buy, but since the national average expenditure for car insurance is $795 a year and PA's average is $820, it can easily be inferred that Pennsylvanians are likely to pay a bit more on average for just about any type of coverage.
To answer that question, airfare shopping engine CheapAir.com monitored fares for more than 4 million flights in 2013 over a booking period ranging from 320 days in advance to one day in advance. Its researchers found that fares for domestic flights were lowest 54 days in advance.
That brings us to the 54 days. For a study published in February, the booking site CheapAir.com looked at millions of trip combinations, searching as far as 320 days in advance to one day prior to departure and every possible day between. Thatâs 1.3 billion airfares. The result: 54 days in advance was the best time, on average, to buy domestic tickets. This is not a hard-and-fast rule, however. Airfares to popular vacation destinations tend to go up sooner.
