Mrs. Catbert10 and I are traveling to LGW for a quick post Christmas vacation. I snagged a couple of reward tickets for IAH – LGW a few months ago. I was unable to get anything out of AUS because of the AUS - IAH segment. Earlier this month, we decided that instead of driving to IAH from Austin, we would fly instead. Mrs. Catbert10 also needs a few more miles to qualify as Silver. We purchased a round-trip AUS-IAH to bookend our IAH-LGW trip. My question regards baggage. Since both itins are on CO, will we be able to check baggage in AUS all the way through to LGW?

TIA
