Best Time to Book Allegiant Air Flights to San Diego


1

Cheapest Months to Travel

September, October, and January offer the lowest fares. Summer is moderate since San Diego doesn't get as hot as inland California. Shoulder seasons bring the best balance of low prices and good weather.

2

Peak Travel Seasons to Avoid

Summer (June to August) and holiday periods see higher prices. Comic-Con in July drives particular demand.

3

Best Time to Book

Book 4 to 8 weeks out. San Diego routes have fewer frequencies than Las Vegas or Orlando, so seats go fast.

4

Midweek Advantage

Midweek departures save $15 to $30 over weekends. Wednesday is typically the cheapest day to fly.

5

Time Difference to Keep in Mind

San Diego runs on Pacific Time (PT). Same as Los Angeles, 3 hours behind New York.

What Cabin Options Are Available on Allegiant Air Flights to San Diego?


Legroom+ in front rows. $10 to $35 per segment.

Bundles available at booking. Carry-on, checked bag, seat, and priority boarding packaged together.
