While doing some research for my summer birthday vacation I came across the latest advice from the experts on when to book. They say that 54 days or 7 weeks before your travel date is the ideal time to book and even more specifically on Tuesday morning or at 3 p.m. They say the airlines post their deals on Monday night and that by Tuesday morning the competitors have tried to match. Also, the worst time is too far in advance or just before your flight date. Good luck!
