I am a big fan of the little sparklite. It is easily packed, the tinder will not deteriorate and it has never failed. It's no flamethrower. Flamethrowers are nice, but a sparklite encourages a little care and deliberation- qualities that make for success. The Ranger Rick unit is better than a damp book of paper matches. I personally found it awkward-bad news in the cold or dark. In any case firemaking options should be redundant. The metal matches that produce sparks when struck by a knife ( or attached hacksaw blade) are the simplest ( no moving parts) but require some tinder either gathered or added. If a commercial flight banned flammables this may be your best carry option. Matches, lighters, various fire pastes, candles and fuels are additional options, but being consumable units are hampered by service life.
