Here’s another e-mail bag item. Off and on, I get news about airlines opening pop-up shops to celebrate new routes or developments. The latest one to do so, I hear, is JetBlue.

Today and tomorrow, November 11 and 12, JetBlue will celebrate the revival of its seasonal service to Palm Springs by going all out retro. The carrier has opened up a temporary Time Travel Agency in New York City’s SoHo district that transports visitors back in time with a Mod Mid-century feel. Find decor and service reflecting this Golden Age of Flight (probably sadly missed) and get the chance to win some swell prizes too.

The address for this Time Travel Agency is at 138 Wooster Street. It’s open Friday, November 11 and Saturday, November 12, from noon to 8 p.m. Sounds groovy.
