Maryland’s 14 Most Annoying Airport Security Line Habits Revealed

For Marylanders heading out of BWI or other airports, the security line can feel like a test of patience. From unprepared travelers to oblivious line-cutters, certain habits turn a routine process into a frustrating ordeal. Based on insights from travelers, airport staff, and online discussions, we’ve compiled the 14 most annoying airport security line habits that Marylanders—and everyone else—should avoid to keep the line moving smoothly.

1. Not Having ID and Boarding Pass Ready

Fumbling for your ID or boarding pass at the checkpoint slows everyone down. Marylanders rushing to catch flights to D.C. or beyond often forget to have these ready, causing delays. Tip: Keep your ID and boarding pass in an easily accessible pocket or phone wallet before joining the line.

2. Ignoring Liquids Rules

Despite clear TSA guidelines, some travelers still pack full-size shampoo bottles or water bottles in carry-ons, triggering bag checks. The 3-1-1 rule (3.4 oz containers in a quart-sized bag, one per person) is non-negotiable. Tip: Double-check your toiletries before packing to avoid holding up the line.

3. Wearing Complicated Outfits

Belts with oversized buckles, boots with endless laces, or layers of jewelry set off metal detectors and require extra screening. Marylanders heading to colder destinations often wear heavy coats or boots that complicate the process. Tip: Opt for slip-on shoes and minimal accessories to breeze through.

4. Forgetting Items in Pockets

Coins, keys, or phones left in pockets lead to repeated trips through the metal detector. This is a common issue at busy airports like BWI, where rushed travelers overlook small items. Tip: Empty all pockets into your carry-on before reaching the scanner.

5. Chatting Instead of Moving

Some travelers treat the security line like a social hour, chatting with companions or on the phone instead of paying attention. This slows the line and frustrates those trying to make tight connections. Tip: Save conversations for after security to keep things moving.

6. Cutting the Line

Whether intentional or accidental, cutting the line—especially without asking—irks everyone. Marylanders have reported seeing this at crowded BWI checkpoints during peak travel times. Tip: If you’re in a rush, politely ask permission or opt for TSA PreCheck.

7. Overloading Bins

Stuffing multiple bags, jackets, and shoes into one bin creates a logjam at the X-ray machine. This habit is especially prevalent during holiday travel seasons at Maryland airports. Tip: Use multiple bins—one for bags, one for personal items—to streamline scanning.

8. Not Listening to TSA Instructions

Ignoring or arguing with TSA agents about rules, like removing laptops or jackets, causes unnecessary delays. Maryland travelers sometimes get flustered and miss clear instructions. Tip: Pay attention to signage and verbal directions to avoid repeat checks.

9. Leaving Belongings Behind

Forgetting items like wallets or watches at the checkpoint forces travelers to backtrack, clogging the line. This is a frequent issue at BWI’s busy terminals. Tip: Do a quick mental checklist (phone, wallet, keys) before leaving the security area.

10. Bringing Prohibited Items

Knives, large scissors, or even snow globes (over 3.4 oz) in carry-ons trigger alarms and bag searches. Marylanders packing souvenirs or work tools often overlook these restrictions. Tip: Check TSA’s “What Can I Bring?” list online before packing.

11. Holding Up the Body Scanner

Stepping into the body scanner with arms down or items in hand leads to rescans, slowing the line. This is a common rookie mistake at Maryland airports. Tip: Follow the pose shown on the scanner (arms up, feet apart) and remove everything from your hands.

12. Traveling with Unruly Kids

Unsupervised kids running around or not following instructions can disrupt the line. Maryland families traveling during school breaks sometimes struggle to manage children at security. Tip: Prep kids beforehand on what to expect and keep them close.

13. Repacking at the Checkpoint

Reorganizing bags or putting on shoes right at the conveyor belt creates a bottleneck. Marylanders in a hurry often repack in the wrong spot, blocking others. Tip: Move to a nearby bench or seating area to reorganize after clearing security.

14. Ignoring TSA PreCheck or CLEAR Lines

Non-PreCheck travelers mistakenly joining the faster TSA PreCheck or CLEAR lines cause confusion and delays. This happens often at BWI, where signage can be missed in the rush. Tip: Confirm your line eligibility and stick to the correct queue.

How Marylanders Can Make Security Smoother

• Enroll in TSA PreCheck: For $78 (valid for 5 years), Marylanders can enjoy shorter lines and simplified screening at BWI and other airports.
• Pack Smart: Place liquids, laptops, and electronics at the top of your bag for easy access.
• Arrive Early: Aim for 2 hours before domestic flights and 3 hours for international to account for busy BWI checkpoints.
• Stay Calm and Courteous: Patience and politeness go a long way in keeping the line stress-free for everyone.
