The Wander-Beauty Carry-On Game Plan

Flying Spirit successfully is really a packing challenge, and we've built the ideal personal-item loadout so you never need to check a bag on a short trip:

Beauty essentials (the space-savers):

• A wander blush-and-glow palette does the work of five products in one slim compact—exactly the kind of multi-use item Spirit's personal item allowance rewards.
• Crème blush beats powder for travel. A dior blush or ysl blush is a splurge-worthy pick that's compact and long-wearing, while elf blush proves you can hit the budget carrier *and* keep your makeup budget tight too.
• Prefer a scent over skincare? A rollerball of tom ford santal blush is TSA-approved and fits the under-seat bag easily.

Outfit strategy:

• Wear your bulkiest layers on the plane and pack a wrinkle-resistant blush pink dress—one piece that works for dinner, a wedding, or a meeting.

Wellness kit:

• Single-serve packets of dairy free protein powder keep you fueled when airport food is overpriced (and count as dry goods, not liquids).
• Traveling in October? Party-size glow sticks glow and masks on halloween accessories weigh almost nothing and make for festive last-minute costumes—just make sure masks follow TSA rules in carry-ons.
• Jet lag wrecking your routine? Squeeze in a glow barre class when you land instead of packing gym gear.
