I'm afraid the situation regarding which immigration line to go through in the US is not straightforward. When we went to Denver and Miami the US immigration guy refused to let DW through the US line with me. In Baltimore and, I think, New York, we could go through together. Maybe the same when we flew to Albuquerque. I can't remember when we flew to Seattle what we did. I think originally DW just went in a different line because she assumed she had to but we asked to go through together as we went to more airports. I know the Denver guy said he didn't have the right equipment for her in the US line.
