Taking the Lead: Sky-High Holiday Airfares

On Monday's Taking the Lead, Ali talked with CNNMoney.com's Poppy Harlow about soaring airfares this holiday season.

We're paying more this year – 18% more, in fact. That's not all, though. You also need to worry about baggage fees, which usually start at around $25 for the first bag. We've got a few tips to get you the best deal.

HOLIDAY FLYING TIPS:

1. Travel on less popular days.
EXAMPLE: Don't fly home the Sunday after Thanksgiving.

2. Try off-peak hours.
EXAMPLE: Leave very early in the morning.

3. Strategize which days to buy.
EXAMPLE: Many airlines post sales on Monday nights, which means you'll probably get the best deals Tuesday through Thursday.

4. Use your miles if you can.
EXAMPLE: Despite blackout dates, there may be seat openings that you can trade in miles for.
