Flight Deals from Dallas to San Diego from $49

When planning your flight from Dallas to San Diego, you'll find the most expensive times to travel in mid-October and during late March, with peak prices soaring to high ranges. Conversely, the late spring and summer months, particularly from late April through September, offer much lower prices, making this a good time to fly. The most significant peak in prices happens around the mid-October timeframe, while one of the best low-price periods is early September. Overall, expect about a $200 to $300 difference between high and low seasons.

For your trip from Dallas to San Diego, the best time to buy tickets is approximately 30 days before departure when prices are at their lowest around $221. Booking earlier, such as 49 to 55 days in advance, may offer similar prices, but if you wait until within 13 days of your departure, expect prices to rise sharply from around $235 to as high as $741, which is significantly more expensive. Therefore, aim to book at least 30 days in advance for the best rates, and be cautious of high last-minute prices, as they can be more than double the price if booked late.
