As per the MSQ the reason an Airship is an unfeasible option is one the Garlean Threat. Despite the fact that you could skirt the land masses themselves that are controlled by Garlean forces doesn't eliminate the possibilities of running into their airships or navy. Eorzean airships are just not equipped to deal with threats unlike their ships. The second reason is a fuel related issue. There currently does not exist an airship of a large enough size within Eorzean control to hold enough fuel to make the trip. This one is a bit impossible to circumvent seeing as there are airships of a large size in Ishgard and under the control of sky pirates, yet apparently these aren't even large enough to make the trip. This indicates that it is most likely not just a size issue, but an engine issue as well. Eorzea just doesn't have the technology to create an engine that could handle it yet, whereas the Garleans do.
This leaves you with the option of making the two month trip by boat, which is the shortest the trip is as the lorebook states this is with favorable winds. You could also possibly piggy back off of someone else taking the trip by aetheryte, but also note the MSQ refers to the sheer aether cost of doing so when talking about the aetheryte in Yanxia. Stating that it would only really be useful to those with immense aether reserves such as the WoL, so remember while teleporting is an option it is not something everyone can even feasibly do. The average person's aether reserves are actually not all that big.

“Sparhawk grinned. "If Martel finds out that he's drinking again, he'll reach down his throat and pull his heart out."Â
"Can you actually do that to a man?"Â
"You can if your arm's long enough, and if you know what you're looking for.[...]â€Â
