Those are exciting news! Flights are still a bit limited but I hope United will fly on a regular basis. In former times, Continental flew Saturdays and Sundays.
Excerpt from your link:
Also on Dec. 20, United plans to expand its Houston-Aruba service. The airline currently offers Saturday Houston-Aruba flights that are scheduled to continue through mid-August 2014. On Dec. 20, the company will resume Saturday service that will continue through early May 2015 and begin service on Sundays for periods of expected higher demand.
We would be thrilled to get the non stop flight from Houston to Aruba! The last couple of years we had to fly to Charlotte then to Aruba. It makes for such a long day. Coming back this year, we didn't get home until after midnight. It's a shame to leave beautiful Aruba so refreshed only to get home so tired.
thanks for the info!
