Last month we flew YX MKE-LAS and DL LAS-SLC on one ticket...tags automatically came out with all the correct information and were through to SLC. Once in LAS, however, they didn't make the 1h15m connection. According to DL baggage in SLC, someone in MKE didn't enter all the appropriate info??? Don't know what it was, or if it's true, but just a heads up.

Every time I've gone to Hawaii we've interlined with NWA and UA, never with any problems. Just be sure to have the airline code ready for the agent...she tried for every to find Island Air (WP) and couldn't, finally after I told her it was WP at least twice, she tried it and it worked...she was quite surprised!
