The Summer Travel Moves Most People Don’t Make Until It’s Too Late

Lock In Flights Before Prices Stop Being Reasonable
Summer airfare doesn’t wait. The window for a genuinely good deal on June, July, or August flights is closing fast, and last-minute bookings will punish you. Google Flights is the sharpest free tool for tracking prices — set alerts for your target dates and let the algorithm do the watching. It shows historical pricing, flags whether the current fare is high or low, and emails you when something drops.

Hopper’s lead economist Hayley Berg is direct about it: plug in your destination and dates now, let Price Watch run. Midweek departures consistently yield the cheapest options. And if you book and the price falls before departure, you can often cancel and rebook at the lower rate depending on your fare type. A flight credit beats nothing.

One more move people skip: choose your seats the moment you book. Every hour you wait, the cabin fills and the options narrow. Same logic applies to hotels — book refundable rates so you can rebook if the price drops, whether you’re paying cash or points.
Your Passport Might Already Be a Problem
Dig it out right now. Most countries require at least six months of remaining validity — not from your departure date, from your return date. If you’re cutting it close, you’re cutting it too close. And check the blank pages while you’re at it: Mexico and Canada need one, China and South Africa need two.

The State Department is currently running four to six weeks for routine renewals and two to three weeks for expedited. That window is tighter than it sounds when summer is weeks away. Factor in your travel dates and act accordingly — there’s no workaround for a passport that won’t get you through customs.
The Security Lines You Don’t Have to Stand In
TSA PreCheck costs $76.75 for five years. Pennies per airport visit. About 99% of members clear security in ten minutes or less — no laptop removal, no shoes off, no digging liquids out of a bag. Nearly 50 credit cards reimburse the application fee entirely, so check your wallet before paying out of pocket.

If your summer involves any international travel, Global Entry is worth the higher fee. It bundles TSA PreCheck and speeds up customs re-entry at U.S. airports and land border crossings. Five-year validity. Children cannot use the lanes without their own membership — no exceptions, no piggyback option.
CLEAR is a separate program entirely. At $209 a year, it uses iris and fingerprint scans to skip the identity-check queue and escort you straight to the front of the screening line. Over 14 million people have enrolled. Delta and United elite members get it free or discounted; several Amex cards credit the full annual cost. At high-traffic airports like JFK and SFO, it’s the difference between sprinting and strolling to the gate.

Global Entry Has a Clock on It
Flip your Global Entry card over. The expiration date is printed on the back and falls on your birthday following the fifth anniversary of your approval. Miss it without filing a renewal and you’re back in the immigration queue with everyone else.

CBP has extended grace periods of up to two years for overdue renewals, but only if you submitted the renewal application before the card expired. File late and you lose the grace period. Check the date, open your account, and file now if you’re within a year of expiration.
Real ID Is Not Optional Anymore
As of May 7, Real ID-compliant identification is required for domestic air travel. Look at the upper corner of your driver’s license. There should be a star. No star means no compliant ID, and no compliant ID means potential problems at the checkpoint.

You’re not completely grounded without one. A valid passport book or card, a state-issued enhanced driver’s license, or a Global Entry card all qualify as acceptable alternatives. But if you’re traveling on a noncompliant license, bring backup documents — a bank statement, a Social Security card — to support an identity check. You can technically still be denied boarding. Don’t find that out the hard way at 5 a.m.
The App That Can Save Your Entire Trip
Download your airline’s app before you leave the house. Log in. Enable push notifications. During delays and cancellations, airlines push updates to app users before announcing anything at the gate. Being first to know is being first to rebook.

The best airline apps let you track checked bags, request standby on an earlier flight, rebook yourself when an itinerary collapses, and chat with a live agent without sitting on hold. During a weather event or a mechanical delay at a connecting hub, that’s not a convenience feature. It’s the only thing standing between you and sleeping on an airport floor.
Lounge Rules Changed and Nobody Warned You
Airport lounge access got quietly more complicated. American Express Centurion Lounge cardholders can now only bring two guests for free if they’ve hit a $75,000 annual spend threshold on their eligible Amex card. Below that, guests pay their own way. What worked last summer may not work this summer.

Read the current guest policy for every lounge you plan to use before you travel. Policies have been tightening across the board as overcrowding pushed issuers to act. A surprise at the lounge door — especially when you’ve promised family members a quiet pre-flight drink — is a genuinely bad way to start a vacation.
