The short answer
Yes, but only in your carry-on. Vapes and e-cigarettes are banned from checked bags because of their lithium batteries. Vape juice must be in containers of 3.4 oz (100 ml) or less in your liquids bag, and you cannot vape on the plane.

Why vapes can’t go in checked bags
The FAA bans e-cigarettes and vaping devices from checked baggage because lithium batteries can overheat and catch fire in the cargo hold, where no one can put it out. In the cabin, crews can respond. This applies to every type: refillable pens, pod systems and disposables.
Watch out at the gate
If the overhead bins fill up and your carry-on is gate-checked, take your vape and any spare batteries out first. Gate-checked bags ride in the hold.
Using it on the plane
Vaping is banned on all US flights and on almost every airline worldwide, including in the lavatory, where smoke detectors will trigger. Keep the device switched off and protected from accidental activation.
