XpresSpa Cancun International Airport, Terminals 2 and 3The Draw
This Starbucks of airport spas is already in Dallas/Ft. Worth, Philadelphia, Pittsburgh, and Raleigh-Durham; outposts in Amsterdam, Atlanta, Houston, Las Vegas, and San Francisco are in the works. Sure, it feels like a chain, but relaxing in Cancun's 1,400-square-foot parlor of blonde wood, soft carpet, and cushy lounge chairs is infinitely better than sitting at the gate.
Get the 25-minute Stress & Tension Eliminator—a vigorous seated massage of the face, scalp, neck, and shoulders ($40).
Request the hour-long Seaweed facial ($110), a milk-and-honey mask, facial massage, and application of firming seaweed serum (XpresSpa uses its own line of products).
Pre-treatment, you'll recline in a Massage Lounger (read: heated, vibrating La-Z-Boy). Don't worry: Your aesthetician will poke you awake.
Open daily, 7am-9pm; 212/750-9595 (main New York office); xpresspa.com

OM Spa Hong Kong International Airport, Regal Airport HotelThe Draw
For a weekday fee of $20 ($25 on weekends), you'll have use of this airport hotel's gym, steam room, and sauna. But the real reason to come is the 72-foot outdoor pool, surrounded by spa cabanas where aestheticians and massage therapists work their mojo.
Weather permitting, take a plunge in the outdoor pool. If it's chilly out, warm up in the indoor hot tub. (The spa sells bathing suits if yours is stuck in a baggage hold.)
Indulge in the two-hour Jet Lag Retreat package, which includes a 30-minute Aromatic Moor Mud Bath, an hour-long Holistic Massage, and a 30-minute Sabai Hot Stone Arm and Leg Massage ($140).
After your treatment or lap swim, have lunch at one of the umbrella-shaded poolside tables.
Absolute Spa Vancouver International Airport, The Fairmont Vancouver Airport HotelThe Draw
With four different locations, Absolute has practically turned this airport into a resort. Choose from a mile-long list of treatments at the attached Fairmont Hotel, or quicker treatments at the smaller locations.
Gals can hit one of the in-terminal branches for a 30-minute Express Manicure ($40) or an even speedier nail-polish change (15 minutes, $30). Scruffy-feeling guys can freshen up with an old-fashioned hot-towel, straight-razor shave (45 minutes, $55).
Head to the Fairmont location for a Hawaiian Lomi Lomi massage with mango-coconut oil ($105 for an hour) or a cellulite-reducing body wrap to offset all those food-court snacks (45 minutes, $110).
Catch a few z's in a private rest suite (available at the in-terminal branches). A half hour in a reclining lounger with an eye pillow and piped-in ambient music ($20) is the next best thing to first class.
Open Sunday-Thursday, 9am-8pm; Friday and Saturday, 9am-9pm; 604/248-2772; absolutespa.com

OraOxygen Calgary International Airport, Departure Level, Air Canada TerminalThe Draw
The nerve center of this sleek, white-on-white spa (one of two; there's also a branch at Detroit Wayne County International Airport) is its Oxygen Lounge, where you can settle into a leather chaise and revive yourself with doses of 95 percent pure oxygen.
Go for a 15-minute oxygen session ($18). You can add an infusion of essential oil to your oxygen supply; peppermint is invigorating, and eucalyptus is great if you're feeling congested.
Retire to one of the two private treatment rooms and indulge in a 90-minute hot-stone therapy massage ($120).
While you're oxygenating, indulge in a simultaneous polish-free manicure ($15) or foot massage ($20).
Blue Lagoon Iceland Keflavik International AirportThe Draw
While it's not the flagship spa (located at the world-famous Blue Lagoon geothermal pools), this tiny outpost offers some of the same treatments and products.
White-knuckle flight?With the 20-minute hand and arm treatment ($60), your parts are soaked in warm geothermal seawater (from the actual Blue Lagoon!), exfoliated with mineral salt crystals and silica mud, and finished with an invigorating massage.
Get a longer (50-minute), more relaxing version of the same treatment for your feet and legs ($130).
Grab a box of Mineral Bath Salt packets to bring with you; for $60 you can re-create a mini Blue Lagoon in your home or hotel-room tub.
Open daily, 5am-6pm; 354/420-8859 (main spa number: 354/420-8800); bluelagoon.com

JetSetter Spa Miami-Dade International Airport, Main TerminalThe Draw
With five private treatment rooms and a lengthy menu of 25-minute treatments, JetSetter (and its sister spa at Boston's Logan Airport) gives hurried travelers great bang for the buck.
The 20-minute Breeze facial, which includes cleansing, toning, a rejuvenating or cream mask, and a quick facial massage, does wonders to reduce those sitting-on-the-tarmac eye bags.
The hour-long Layover Package ($80) combines a 25-minute anti-aging or antioxidant facial, a 25-minute antistress pedicure, and a 10-minute chair massage.
Grab a quick catnap in one of the JetSetter "sleep pods." You'll recline in a space-agey-looking lounger, where a private soundproof shield descends over your face, and music lulls you to a 30-minute sleep ($15).
d_parture Spa Newark Liberty International Airport, Terminal CThe Draw
This spa's two Newark branches (and another at Orlando International Airport) literally help get your head in the right place after a long flight. As well as mani-pedi stations and private rooms for massage and facials, the spas each include full-service hair salons for cuts, color, and styling.
Men's 20-minute business or buzz cuts cost $25; women can get a 30-minute shampoo and style for $35.
Women's haircuts start at $50; an additional scalp and eye massage that reduces eye puffiness, stuffed sinuses, and stress costs $40.
If plane-cabin static has left you looking like Don King, add a deep-conditioning treatment to your hair service (10 minutes, $10).
