Planning family travel can get expensive fast, but I’ve found the Southwest Airlines Low-Fare Calendar makes it easier to keep costs under control. When booking for four people, even a small difference in price adds up quickly. By checking the calendar, I’ve been able to shift our travel dates by a day or two and save hundreds overall. The tool shows the lowest fares for each day of the month, so you can quickly decide when it’s best to fly. I highly recommend it for families or groups trying to budget travel more effectively. Anyone else here rely on it for larger group bookings?
