Airport terminals are loud, chaotic places. If the extra stimulation adds to your anxiety, a lounge pass is a worthwhile investment. For about $50 to $75, you'll be able to wait for your flight in a quiet, soothing environment. Sip a glass of wine and indulge in a selection of snacks until it's time to go to the gate.
Do your research — some lounges provide massages, nap rooms, and showers for an extra relaxing experience. Choose a lounge you're excited about; the anticipation will displace some of your worry.
