Though we have notification set up in case there are any changes, we were not notified of time changes on both of our upcoming Aruba flights. We still have 6 months to go before we depart so will not be surprised if flight times change again.
I also check to ensure that we still have our seat assignments. One of the other times when we flew over the Christmas holidays, Delta changed the equipment larger planes and assigned seats for everyone were lost. Again, we received no notification but saw it because we kept an eye on it. Luckily, we were able to grab new seats, together for our family of three.
