DTW-SAN, DTW-LAS, and returns, all $25. DTW-SLC, $20. Looks like T-24 for me. At $30 RT, EB was barely worth it. It's very rare that I cannot check in at T-24. And in cases where we're traveling with the family (SAN, SLC), we get family boarding anyway, so no worse than A-61 (effectively). WN just priced this out of the realm of what the convenience is worth.
