Equinox teamed with Delta Airlines for a unique "Sweatlag" promotion. The partnership promoted Sweatlag as a workout scientifically designed to beat jet lag, from Delta and Equinox. They created the first exercise routine that’s scientifically designed to beat jet lag. In addition to the routine, there were also select Sweatlag classes taught at select Equinox locations. When Delta passengers returned from trips, their boarding pass gave them exclusive access to a Sweatlag class at Equinox. Booking was available for each class online one week in advance. The promotion was only available in Los Angeles.
