Real Cost Comparison

Let's compare that $89 "cheap" flight with a $149 full-service option:

How to Find True Deals

1. Use Total Cost Calculators

Always factor in your likely add-ons. If you need a carry-on and prefer to choose your seat, include those costs upfront.

2. Read the Fine Print

Basic economy often means:

• No seat selection (you get what's left)
• No changes allowed
• Board last (overhead space may be full)
• No frequent flyer miles or upgrades

3. Compare Apples to Apples

Configure each airline's booking with the same add-ons to see true cost differences.

When Budget Airlines Win

Ultra-low-cost carriers can be genuinely cheaper if you travel light and flexible. For more money-saving strategies, check our guide on cheap flights from Seattle. Budget airlines work best when you:

• Travel with just a personal item
• Don't mind random seat assignment
• Book direct (no changes needed)
• Bring your own snacks

Pro Tip: Use Alerts Wisely

Set price alerts for both basic and full-service fare types. Sometimes "expensive" airlines have sales that beat budget options even after fees. Our January 2025 predictions show how major carriers often undercut budget airlines during sale periods.
