The past few times i flew with united and used my BMI to get free bags, i showed my BMI card at check in. Is there a way to add the number to the UA reservation before i get to the airport and still earn the UA miles using my mileage plus #?
When i show the BMI card at the airport, they are always wondering why it wasn't added beforehand...
yep simply use your BMI # when you make the res then at the Gate or Club if you access ask that they switch it to your UA# or whatever Carrier you want.
then you will have to repeat it again after the flight credit has posted for the return, going back in and changing it back to BMI and then again after checking in have them at the Gate or Club change it to UA
What to do if the return is before the Outbound has posted, a good question, Id probably leave the UA # in the res and go thru the hassle at checkin
I did this when I was flyingon CO metal and wanted the EUA but wanted the EQMs to go to UA, I simply changed it at the Gate, for my return FC was soldout so I left UA in there
