Let me write a detailed answer for you. You should read this content line by line and I am sure ultimately you will have no doubt in understanding whether archaebacteria have flagella or not. So, let's start !
First of all, you need to know that Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this classification is obsolete. Archaea and bacteria have generally similar cell structure, but cell composition and organization set the archaea apart. Like bacteria, archaea lack interior membranes and organelles. Like bacteria, the cell membranes of archaea are usually bounded by a cell wall and they swim using one or more flagella. Structurally, archaea are most similar to gram-positive bacteria. Most have a single plasma membrane and cell wall, and lack a periplasmic space; the exception to this general rule is Ignicoccus, which possess a particularly large periplasm that contains membrane-bound vesicles and is enclosed by an outer membrane.
Remember, Archaeal flagella are smaller, not hollow, frequently have sugar molecules attached, used for movement. Bacterial flagella are bigger, hollow, doesn't have sugar molecules attached and is used for movement.
CONCLUSION : Both archaea and bacteria have flagella, thread-like structures that allow organisms to move by propelling them through their environment. Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim.
MORE TO KNOW :
(i) Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota.
(ii) Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat and square cells of Haloquadratum walsbyi. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved in transcription and translation.
(iii) Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
