You can readily identify an e-Passport, because it has a unique international symbol on the cover. Electronic System for Travel Authorization (ESTA) ESTA is an automated system that determines the eligibility of visitors to travel to the United States under the Visa Waiver Program (VWP). Authorization via ESTA does not determine whether a traveler is admissible to the United States.
Two to three weeks before the flight date, the price quotes start increasing. This is the time when business travelers start booking. While price drops are still possible, a chance of a price increase is much higher if you wait to book within this time period.
The report is even broken down by destination. Expedia says air ticket prices in 2015 are expected to drop 4.4% for flights to Las Vegas, 1.7% for flights to New York and 1.8% for flights to Orlando. If you want to save the most, fly to Dallas. Those tickets are expected to drop 11.2%. Expedia has even more good news: It will be cheaper to fly in premium cabins.
