🔎 Best Tools to Track Flights

Use these tools to monitor flight trends and set price drop alerts:

• Google Flights – Best for flexible calendars & historical pricing
• Hopper – Color-coded price predictions and watchlists
• Skyscanner – Great for flexible destinations & multi-airport comparisons
• Going (formerly Scott’s Cheap Flights) – Finds error fares & flash deals

Combine 2–3 of these tools to increase your chances of spotting a price dip.

🧠 Flexible Booking Hacks for Families

• Use “everywhere” search – Skyscanner lets you search cheapest destinations from your airport
• Depart mid-week – Tuesday and Wednesday flights are usually cheaper than weekends
• Consider alternate airports – Flying out of Oakland vs. SFO, or Long Beach vs. LAX can cut costs by 15–30%
• Split tickets – Sometimes booking one-ways (or 2 adults + 2 kids separately) gives better pricing
• Free cancellation – Choose airlines or credit cards that offer 24–48 hour hold/refund windows

⚠️ 5 Mistakes to Avoid When Booking Summer Flights

1. Waiting too long – Summer flights only get more expensive closer to departure.
2. Booking without comparison – Always check at least 2 flight engines (e.g., Google Flights + Hopper).
3. Ignoring bag fees – Some cheap fares don’t include carry-ons or seat selection.
4. Flying on weekends only – Friday and Sunday flights tend to be highest in demand and cost.
5. Forgetting about school calendars – Prices spike the moment school ends — fly a few days before or after if possible.

❓ FAQ – Booking Flights for Summer 2025

1. What’s the absolute cheapest day to fly in summer?
Tuesdays and Wednesdays are consistently cheapest for both domestic and international flights.

2. How far in advance should I book?
Domestic: 60–90 days out.
International: 3–6 months in advance.

3. Should I use incognito mode when searching flights?
Not necessary. Price changes are more about demand than cookies — but clearing cache doesn’t hurt.

4. What if I need to fly during a school holiday?
Try early morning or late evening flights for lower prices. Set alerts 3–4 months ahead.

5. Do kids always get discounts?
Not always. Children under 2 fly free (lap infant), but older kids pay similar rates. Check airline policies.

6. Should I book one-way or round-trip flights?
Try both! Sometimes one-ways are cheaper or let you mix airlines for savings.

7. Is basic economy a good deal for families?
Usually not — no seat selection, no carry-on, and no refunds. Only book if you’re traveling very light.

8. Can credit card points really help?
Yes! Even partial redemptions can save hundreds. Use cards with travel portals or airline partners.

9. How do I handle delays or cancellations with kids?
Pack snacks, games, and use airline apps for rebooking. Travel insurance can help cover overnight stays or rebooking costs.
