I'm flying next week (EWR to DFW) using CO miles but on a Delta flight. (First time I've used miles, btw.) Unavoidably, I'll have a large trunk, which I should be able to keep under 70 pounds.
Continental's site says:
When a customer travels on a codeshare flight or on an aircraft operated by a SkyTeam Alliance partner, then the policy regarding checked bags follows the rules determined by the originating operating carrier.
Who's the "originating operating carrier?" The fees are much more expensive on Delta.
With Continental's fees, it's cheaper to take the trunk with me than to ship it...but Delta's fees may make it a toss-up.
The outbound flight also involves changing planes in Cincinnati, but I'm assuming I only have to pay the baggage fees once.
Thanks in advance for your guidance.
