Check Airline Rules

Every airline plays by different rules. Check before you pack. Getting it wrong at the desk is costly. Every airline has different baggage allowances. Review:

• Personal item dimensions

Weigh Bags Before Departure

Weigh everything at home. Fees for overweight bags are steep. Finding out at the airport is the worst way to learn.

Pack Essential Items in Carry-On

Keep the important stuff close. Always. Include:

• Travel documents
• Medications
• Electronics
• Chargers
• Change of clothes

Follow Security Regulations

Liquids generally must comply with airport security restrictions.

Label Your Luggage

Label everything clearly. Delayed bags find their way back faster when they’re easy to spot. Simple step. Always worth doing.

Use Fare Alerts

Set up price alerts. Let the tools do the watching. You’ll hear when fares drop without having to check every day.

Travel During Off-Peak Seasons

Autumn and winter mean lower fares. If your schedule has room, shifting your dates saves real money.

Consider Connecting Flights

Connections take longer. But they often cost less. Worth it if you’re not in a rush.

Redeem Airline Miles

Use your points. Miles can cut costs in a big way. No point letting them sit there doing nothing.

Travel Light

Skip the checked bag if you can. Baggage fees on international routes add up. Traveling light keeps more money in your pocket.
