I'm taking a flight SFO-LAS next week for a backpacking trip and I'm planning to bring a previously-used backpacking stove (the stove will be well purged and without any fuel). I called Premier Reservations and after being on hold for a long time they told me that it was Ok to check it with my bags. However, the person I talked to didn't sound very confident.

Does anybody have had any problems checking backpacking stoves in UAL flights?

Thanks!
