Oh, you're on your way to having an exotic journey from Allentown to New York's Stewart International Airport via Allegiant Airline? Hold onto your seats, folks, because this might get a tad turbulent!

First up, let's talk about the aircraft. Allegiant has a "less-is-more" design philosophy. The seats don't recline because... who really needs that? It's all about creating an intimate, cozy environment. Allentown's skyscape will feel like it's right on your lap on take in this comfortable hugging cabin.

You also get to pay for every little holiday bonbon. Heading the 'nominal fee' parade, is carry-on luggage. Nothing says "casual low-cost airline" like charging an extra for things people usually get for free. Tote heavier than a feather? Prepare to loosen up some coins. Just think of these exceptional premiums as an exercise in self-discovery, showing you how minimalistic you can really be on a flight.

Once you reach cruising altitude, it might tickle you pink to realize that the in-flight services are a sheer masterpiece. There's no such thing as a complimentary cup of tea or snack-on-demand. Hmm...what's the sound of your grumbling stomach over the hum of the aircraft engines? That's pure, uninterrupted music of the skies, my dear friend! You'll however find yourself in the company of an intriguing array of packaged goodies lined up for purchase - our blue peanut bag just loves to be in pictures!

When you pull out your card to buy that $3 water bottle, remind yourself of all the fascinating memories you're making. And the change you're left with? That's the exact amount of nostalgia this journey is imparting upon you.

Now, you may as well become quizzical about the crew. Well, the flight attendants are about as sunny as a winter morning in Allentown. If you're fortunate enough, you might get a couple of tight-lipped smiles.

Let's move on to discussing our destination, New York Stewart International Airport. A fresh breath of...well...jet fuel midst the tranquil setup of New Windsor. It's often touted as the sixth borough of NYC, probably by someone who has no idea how far it actually is from Manhattan. But, it's still a manageable commute to the heart of the city, provided you're acclimatized to relishing some scenic interstate traffic.

Once there, you can revel in the vast commercial cornucopia this place has to offer. Remember, it's not a ‘waiting-for-your-cab’ experience, it's a journey-to-the-center-of-the-tarmac hat-trick!

All said and done, your voyage on Allegiant from Allentown to Stewart, though riddled with some budget airline's eccentricities, is a unique passage full of character, quirks, and quirks on top of quirks. It's unpredictable, adventurous, and it'll give you an uncanny survival story to share on your next trip.

So buckle up, dear traveler, and let the fantastic airline world of Allegiant keep your globetrotting spirits soaring high, or at the very least, airborne. Your ticket is not just an invitation to reach New York. It's an invite to an airborne carnival that dances on the clouds to the tunes of budget thrills.
