The Airport Dual-Hub Reality and Baggage Traps

Do not just look at the ticket price when booking your flight from Kolkata. You need to know exactly where you are landing because Bangkok has two active airports, and they are on opposite sides of the city.

If you book Air India or Thai Airways, you will land at Suvarnabhumi Airport (BKK). This is the premium hub. The best part about BKK is the Airport Rail Link, which lets you bypass Bangkok’s legendary traffic jams completely and get straight to the city center for around ₹50–₹160 (~$0.50–$1.70).

If you choose a budget carrier like Thai AirAsia, you will land at Don Mueang International Airport (DMK). DMK handles most regional low-cost traffic.

Budget carriers on this route are absolutely brutal about the standard 7kg cabin luggage restriction. Do not try to sneak an extra gym bag or a heavy backpack past them. They frequently conduct mandatory weigh-ins right at the Kolkata boarding gates. If your bag clocks in at 8kg, they will slap you with heavy penalties on the spot. Pack light, or pay for your check-in luggage online in advance.

Watch out for phishing flight scams before you even reach CCU. Scammers send highly sophisticated fake booking cancellation SMS or emails claiming there is an operational issue with your flight. They will demand a “re-issuance fee” to secure your seat. If you get one of these messages, do not click any links. Log in directly to the official airline portal to independently verify your PNR status.

Arriving in Bangkok: Taxis and Transit

The moment you clear customs and walk out into the arrival hall, you will be approached by aggressive touts. They will stand near official-looking desks and try to sell you a private “limousine” or a flat-rate taxi ride to your hotel for 1,200 THB to 1,500 THB (~₹2,850–₹3,570 / ~$34–$42). Ignore them completely.

Walk down to Level 1 and locate the automated public metered taxi queues. You pull a ticket from a machine, walk to the designated lane number, and meet your driver. A real metered taxi to the city center costs around 300 THB to 450 THB ($8.50–$12.80) plus a 50 THB ($1.40) airport surcharge.

If your driver rolls out of the airport and claims the “meter is broken,” tell them firmly to turn it on or drop you off immediately at the next safe spot. Better yet, download the Grab or Bolt apps on your phone using airport Wi-Fi to book a ride with a fixed price.

To get connected immediately, buy a local tourist SIM card right at the airport or pre-book an e-SIM. A standard 10–14 day data plan from providers like AIS or dtac costs around ₹950–₹1,100 (~$10–$12) and gives you enough data for navigation and ride-hailing apps.

Vegetarian and Jain Survival Guide

You will hear people tell you that finding vegetarian food in Thailand is impossible because of the fish sauce. They are wrong, but you do need a strategy. Do not just walk into a random alley and expect the vendor to understand what “vegetarian” means.

Your ultimate secret weapon is the Thai word “Jay” (กินเจ — pronounced gin jay). This does not just mean vegetarian; it means strict vegan and explicitly excludes onions and garlic, making it perfect for Jain travelers. When you see a street food stall displaying a bright yellow flag with red Thai characters, that is a certified “Jay” stall.

[Yellow Flag with Red Text] = Safe "Jay" (Vegan / Jain-Friendly) Food

If you want a break from decoding menus, head straight to lower Sukhumvit Road (specifically Soi 11) or the area around Indra Square in Pratunam. These neighborhoods are massive hubs for the Indian diaspora and are packed with authentic Indian joints. You can get an excellent meal at places like Chowpati or Sri Ganesha without any language barriers.

A standard street food meal like Pad Thai, vegetable fried rice, or a simple noodle soup costs between 50 THB and 100 THB, which translates to roughly ₹140–₹290 ($1.50–$3.00). If you opt for local mall food courts or sit-down mid-range restaurants, expect to spend anywhere from 60 THB to 400 THB ($1.70–$11.40) per meal.

What to Pack and How to Dress

Bangkok is hot and humid year-round, but you cannot dress like you are heading to a Goa beach if you want to see the sights.

Sacred sites like Wat Arun or the Grand Palace enforce an incredibly strict entry dress code. If you show up in shorts, a sleeveless shirt, tight gym tights, or revealing sportswear, the guards will deny you entry immediately. Your shoulders and knees must be fully covered.

Pack lightweight, breathable cotton trousers, linen shirts, maxi skirts, or a couple of lightweight sarongs that you can easily throw into your daypack and wrap around yourself before entering a temple.

Essential Packing Checklist

• Clothing: 3–4 lightweight cotton t-shirts, 2 pairs of loose linen or cotton trousers, 1 linen shirt, and a light jacket (the mall and transit AC is freezing).
• Footwear: Slip-on shoes or comfortable sandals. You have to take your shoes off frequently before entering temple halls and even some local shops.
• Electronics: A 10,000 mAh power bank (mandatory for long days navigating), and a standard Indian two-pin plug works perfectly in most Thai sockets, but a universal adapter avoids loose-connection drama.

Common Mistakes Indians Make

The Airport Currency Exchange Trap

Many Indian backpackers make the mistake of changing their Indian Rupees (INR) at Kolkata Airport or right after landing at Bangkok airports. The rates at these transit hubs are atrocious and you will lose a massive chunk of your budget. Change just a nominal amount in Kolkata to handle your basic arrival taxi or train fees. Once you are in downtown Bangkok, head to an urban money-changing chain like SuperRich (look for their bright orange or green booths) to get the premium market rates for your cash.

The Customs Co-Carrying Blunder

If you are traveling with a group of friends or family, never let one person carry all the duty-free alcohol or tobacco purchases through the green channel. Bangkok customs officials are incredibly strict and actively police this. The legal limit is exactly 1 liter of alcohol and 200 cigarettes per individual traveler. If a customs officer stops your group and finds 4 bottles of liquor or 600 cigarettes inside a single person’s backpack, they will treat it as smuggling. They do not care if it belongs to the whole group. They will confiscate everything and slap you with dynamic fines that easily scale over ₹57,000 USD (~$600).

The Impossibly Cheap Tuk-Tuk Offer

If a friendly local or a smooth-talking Tuk-Tuk driver approaches you near a major tourist site and offers a city tour for an impossibly cheap price like 20 THB (~₹48 / ~$0.60), walk away. This is the setup for a high-pressure sales scam. They will take you to a series of shady gemstone storefronts, tailor shops, or fake export centers where aggressive salesmen will pressure you into buying overpriced goods. Stick to app-based rides or negotiate a realistic price based on distance.

What Most Guides Don’t Tell You

The Immigration “Show-Money” Audit

Thai immigration officers randomly audit tourists entering on tourist tracks to verify they have sufficient funds for their stay. They do not care about your banking app screen or credit card limits. They want to see physical cash. You are legally required to carry up to 10,000 THB (~₹24,000 / $285) per person or 20,000 THB (₹48,000 / ~$570) per family in any major currency (INR, USD, or THB). Keep this cash safely in your pocket or pouch before you line up at the immigration counter just in case you are picked for a random check.

The “Grand Palace is Closed” Street Routine

This is one of the oldest tricks in the book, yet people still fall for it every day. As you approach the Grand Palace or Wat Pho, a well-dressed local might approach you politely and inform you that the temple is closed today for a “royal holiday,” “cleaning,” or a “special monk ceremony.” They will then immediately offer to call their friend who drives a Tuk-Tuk to take you to alternative temples. The palace is almost certainly open. Walk past them directly to the official ticket counter to check for yourself.
