Traveling ABQ-ATL-SAV. We were 2+ hours late leaving ABQ which was going to leave us 10 minutes to make our connection. They our gate as E concourse and connecting was B. Well we pulled in and the pilot said there was a gate change and we were now at B12 and my connecting flight was leaving from B14! We walked off one plane and boarded the next. Luckily we were flying first so our SAV flight new of our new gate and held the door open for us.
