Thanks in advance for any suggestions. One-way trip from MEX to OSL in economy, and I would love to do a 1-3 day stopover, if possible, in Detroit (DTW) or another nearby US city. I need to arrive in Oslo by 6/22, and I can leave MEX as early as 6/19. I have been collecting points for several months, but this is my first complicated award booking! I have 80K + balances in Amex, Chase ultimate rewards, and AAdvantage. How can I best use these to get a good value and the stopover? Thanks! p.s. alternatively, a 1-3 day stopover in Madrid would be great, too.
