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.
However, Filip Filipov of Skyscanner advises that while five weeks is the average, the optimum time to book your flight can vary significantly between destinations. Price patterns can vary by type of airline and between short and long haul travel, so is very much destination dependent.. The best time for flights to Turkey, for example, is 13 weeks before departure, while the US should be booked five months (21 weeks) ahead. Skyscanner's research covers scheduled and low-cost flights (charter flights represented less than 1.5%), and is contrary to the advice given by most industry experts who say, when it comes to full-service scheduled flights, the golden rule is the earlier the better.
