Flights from New York to San Diego average $320-$450 roundtrip during peak season, according to Google Flights data from 2023. You can snag a $299 one-way deal on United in February, but avoid Spirit Airlines’ $119 base fare—they’ll charge $60 for a carry-on.
Delta’s $380 economy fare from Atlanta includes a free checked bag, while American’s $410 coach seat has no legroom. I’ve seen prices spike $150+ when booking last-minute—always check prices 3 months ahead.
SAN (San Diego International) is the only airport serving downtown, just 12 miles from the Gaslamp Quarter. You’ll save 25 minutes versus flying into Los Angeles (LAX), which is 70 miles away with a $50+ shuttle fee.
Don’t waste time at MRY (McClellan-Palomar Airport) unless you’re flying a private jet—only one airline (Alaska) uses it, and it’s 30 miles from the beach. SAN’s terminal has direct access to the trolley, making it effortless to reach your hotel.
February is the cheapest month, with average roundtrip fares from Chicago at $280 on United. March and April are $300-$350, but you’ll face crowds at La Jolla Shores and Balboa Park.
Avoid June and August—prices jump to $450+ for the same route. I learned this the hard way when my family paid $520 for a July trip. Stick to February or October for sweet spots: lower prices and mild weather (65-75°F).
United, American, Delta, Alaska, and Southwest all serve SAN daily. United’s 8:00 a.m. flight from Newark (EWR) costs $390 with 32" seat pitch, while Spirit’s $120 flight has 28" pitch and charges $35 for a carry-on.
Alaska Airlines is my top pick for comfort—$420 from Portland with free checked bags and a 32" seat pitch. Avoid Frontier: I’ve seen their $150 fare turn into $210 with fees, and the seats are cramped. Southwest’s $350 fare from Dallas includes two free bags but has only 30" pitch.
Book direct with United or Alaska—both include one free checked bag in economy. Spirit and Frontier charge $35-$60 for the first bag, and their fees add up fast if you’re traveling with kids.
Always check your fare class before booking. A United Basic Economy ticket costs $220 but has no baggage allowance. I once paid $70 for a carry-on bag on a $199 Spirit flight—never again. Use the airline’s app to check baggage rules before you fly.
A: February. Flights from New York average $280 roundtrip, and you’ll avoid summer crowds. The weather’s perfect for beach walks too—highs in the mid-60s.
A: SAN, hands down. It’s 12 miles to downtown, while LAX is 70 miles away. You’ll spend $20 less on a taxi and avoid 45 minutes of traffic every time you go to the beach.
A: Only in February with United or American. I found a $299 roundtrip from Boston on United last February—book early, and avoid weekends. Any cheaper deal means Spirit, which will charge you for everything else.
