Airport delays, flight cancellations, and long waits in the security line are some of the not-so-welcome gifts we get during the holiday season. Though we can’t avoid all holiday travel snafus, we can be prepared because our smartphones are a great resource. Check out this list of apps and other services that can help.

Your airline’s app 
Flight status, gate changes, alerts, nearby lounge info, and your mobile boarding pass—you’ll get all of these through your airline’s app.

Tracking flight delays and cancellations
Apps like FlightStats and FlightAware track flight status and can alert you to delays or weather cancellations, sometimes more efficiently than the airline will. If your flight does get cancelled due to a storm and you want to do what I do—which is to find alternate flights that connect in cities that are having no weather issues—they can tell you which large hubs are unaffected by the current weather situation.

An app for monitoring the wait at airport security lines
The line at security used to be one of the most unpredictable pain points in your journey. Luckily, that has changed, because a few apps can now show you what to expect. The TSA’s official MyTSA app shows you estimated wait times, provides tips on what you can and cannot bring through security, and has a handy “Ask TSA” live-chat feature. MiFlight has real-time info crowd-sourced from fellow travelers using the app (available on iPhone only). App in the Air crowdsources wait times too. You can also check the website of the airport; some (like JFK, EWR, and ATL) offer real-time waits at security and customs.  

Real-time updates and answers from your airline
X (formerly Twitter) may have its flaws, but following your airline’s feed is typically one of the quickest ways to find out about delays or cancellations. It can also be an effective way to get in touch with an airline rep fast: Direct your question or complaint to the airline’s social media, and they’re incentivized to give you a speedy answer.

Emergency airline assistance
Cranky Concierge isn’t an app—it’s a website and (gasp!) a phone service—but when your flight is canceled or delayed, and you really need to get where you’re going, this is the help you need. Sure, you could choose to spend frustrating hours on the phone with unhelpful airline customer-service centers, trying to reroute your own trip—or you could let the Cranky team handle it. They have knowledge of and access to info you won’t be able to get on your own, and they can research and rebook you with the best possible option while you get a drink at the airport bar. Cranky Concierge’s urgent assistance service starts at $175 and is accessible through the website and via phone (U.S.: 888-747-1011 x9; global: +1-74-200-4200 x9).

Finding an airport lounge 
You no longer need to hold special status or specific credit cards to access certain airport lounges—just pay a fee and you’re entitled to all the comfy couches, free Wi-Fi, and complimentary snacks the elite travelers get. LoungeBuddy (available for iPhone only) will help you find these pay-for-the-day enclaves, show you photos and reviews posted by other travelers, and let you book a spot in advance when possible. And if you do have special access via a credit card or frequent-flier program, LoungeBuddy can store your info and let you know when those free-access lounges are nearby too.

Priority Pass is a lounge subscription service. For an annual membership fee between $99 and $469, Priority Pass grants its members access to over 1,300 airport lounges and experiences worldwide. Some credit cards, such as American Express Platinum, Chase Sapphire Reserve, and certain Capital One cards, offer Priority Pass membership as a free perk, so check out your card’s benefits package before signing up.

Navigating the airport
FLIO covers nearly 6,000 airports globally, connecting you with information on the airport you’re in—everything from where to find power outlets to hotels that offer day-use rooms for long layovers. Services featured vary, depending on the airport. A check of services offered at Newark International Airport (EWR) includes details on where to find nursing suites and how to transfer to other New York-area airports. In Chile’s Santiago airport (SCL), you can find lounges and luggage storage. And at Amsterdam’s Schiphol Airport, the app tips you off to baby lounges, an in-airport park, and locations of massage chairs. It’s helpful to know your airport’s IATA code, since airports are listed alphabetically by their three-letter code, and these aren’t always obvious.

A quicker Global Entry experience in some airports
If you already have a Global Entry membership and are re-entering the U.S. via Seattle, Los Angeles, Miami, Orlando, Washington Dulles, Pittsburgh, or Houston, you can use an app that Customs and Border Protection is testing: Instead of stopping at a kiosk, you take a selfie with the app and then go straight to the CBP officers to complete your arrival processing.

When you don’t speak the language
When you’re struggling to communicate with a taxi driver, a good translation app can be a godsend. Google Translate lets you speak right into the phone, and then it can translate, out loud, into the selected language. The app’s Google Lens function also decodes written text via your phone’s camera—super-handy for reading menus or museum display panels—and it’s all available offline with dozens of downloadable language dictionaries. Another good option is Apple’s Translate; it features type, voice, or picture translation, like Google, but only offers 17 languages at the moment.

Last-minute hotel stays if your flight is delayed
Sometimes things don’t go as planned, or maybe you didn’t plan at all, and you need a hotel room right now. HotelTonight is made for those times, offering last-minute discounts on hotels of various star levels. The app doesn’t cover every destination in the world, but it does include a lot of big cities and popular travel spots in the U.S. and overseas. One helpful feature is that it sorts urban areas both by neighborhoods and by airports.

Getting to or from the airport, or anywhere else
When you need a ride and you don’t want to drive (or shouldn’t), Uber and Lyft are still the go-to rideshare apps every traveler should have in their phone. Uber is particularly useful in many other countries around the world.

Another alternative to airport taxis
Landing in an airport in an unfamiliar city can be an unsettling experience if ridesharing is banned and you have no idea how reliable or reputable the taxis are. Welcome Pickups contracts with drivers and limo companies in 160 cities worldwide, and you can schedule a transfer from their app or site in seconds. For roughly the price of a local taxi, your driver will meet you at baggage claim or in a specified area and deliver you to your destination. Communication is done within the app, and you can pay by credit card.

Calling and texting for free
Forego costly international calling charges and use WhatsApp to communicate when you’re abroad—both with friends and family back home, and with your private guide or other locals in your destination. With WhatsApp, texts and calls are free anytime your phone is connected to Wi-Fi.

Restaurant reservations 
The last thing a weary traveler wants after a long flight is to have to wander the streets looking for a meal. Google and Apple Maps will show you highly rated restaurants in your area, but I love the ease of the reservation app OpenTable to book a table. Particularly helpful, especially when visiting a new city, is the “near me” function. OpenTable, already well entrenched in the U.S., is expanding its international footprint and now serving countries such as the U.K., India, Singapore, Mexico, Australia, Italy, and beyond. One tip: You will want to establish your free account before you leave home.

Maps and navigation
What makes Maps.me so useful is that it offers complete city and country downloads, perfect for touching down in a foreign country where you don’t want to incur roaming data fees.

Getting around town and beyond
Rome2Rio incorporates public transportation schedules with drive, walk, and even scooter/bike times to give you step-by-step travel options in each format within a clean, clear interface. It’ll even tell you which train car to ride in and what subway exit to take. It’s not just city-focused; you can plan trips between cities, and Rome2Rio will offer recommendations of flights, trains, and buses, along with how much they cost.

Calculating currency conversions
An app like Currency lets you skip the mental math of currency conversions—and it saves the latest conversion rate so that it works offline too.
