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.
On most airlines, flights open up for sale 331 days in advance. That is the earliest you can book a flight â about 11 months in advance. We found that for about four months from that time, domestic fares tended to stay pretty steady, and pretty high. That makes sense.
