Jet2 vs TUI 2026: Which Package Holiday Airline Wins?

Jet2 and TUI Airways are the UK’s two package-holiday heavyweights, and 2026 finds them moving in opposite directions. Jet2holidays has overtaken TUI as the UK’s largest tour operator, Jet2 tops the Which? airline survey for the eleventh straight year, and its new Gatwick base puts new A321neos on TUI’s southern doorstep. TUI, meanwhile, spent the year defending headlines about being the UK’s most delayed major airline.

The verdict is direct: for the classic short and mid-haul package, Spain, Greece, Turkey, the Canaries, Jet2 is the better airline and it is not close. It flew 68 percent of flights on time in the year to April 2025; TUI managed 59.2 percent, the worst of the big six UK carriers on CAA data. Both include 10 kg hand luggage, both bundle hold bags into packages, both will get your transfer coach waiting. TUI stays firmly in the game for one reason: it sells trips Jet2 simply does not, 787 long-haul to the Caribbean, Mexico, and Florida, and cruise packages around Marella. Pick the destination first; if both airlines fly it, pick Jet2.

What We Looked For

These two are bought as holidays, not flights, so we compared them the way a family books them:

• Punctuality and cancellations, the area where these two have diverged most sharply
• Hand luggage and the included package luggage, since almost nobody flies these airlines flight-only
• Package quality and protection, transfers, ATOL, and what the brands include by default
• Network reach, where TUI’s long-haul and cruise program changes the conversation
• Independent satisfaction data, the Which? survey and its disruption-handling detail
• Flight-only value, for the minority using these as plain airlines

Reliability got the heaviest weight. A package holiday is a fixed week; a four-hour delay eats a day of it.

Is Jet2 or TUI more punctual?

Jet2 by the widest margin in UK aviation: 68 percent on time against TUI’s 59.2 percent. But TUI almost never outright cancels.

UK CAA data for the year to April 2025, as analyzed by Which?:

• Jet2: roughly 68 percent of flights on time, 0.12 percent cancelled
• TUI Airways: 59.2 percent on time, the worst of the six big UK airlines, 0.21 percent cancelled

Independent analyses of January to September 2025 put TUI’s on-time rate around 57 percent, so this is a pattern, not a bad month. TUI’s own defense is revealing: it argues that unlike rivals it delays flights and swaps in replacement aircraft rather than cancelling, so passengers still fly. The cancellation number backs that up, 0.21 percent is genuinely low, and on a package holiday “late but flying” beats “cancelled” every time. But Jet2 manages both: the better cancellation rate and nearly nine points more punctuality.

The Which? survey context makes the same point from passenger experience: Jet2 scored 76 percent and took Recommended Provider status; TUI’s delays were prominent enough that Which? titled its analysis around them.

If it does go wrong, both are UK carriers: a 3+ hour arrival delay or short-notice cancellation within the airline’s control owes you UK261 compensation of £220 to £520, on top of the holiday, and TUI’s delay-heavy profile is exactly the pattern UK261 exists for.

Winner: punctuality

Jet2 / 68% vs 59.2% on time (UK CAA, year to April 2025)

Winner: cancellations

Tie / 0.12% vs 0.21%, both excellent

Winner: delay length risk

Jet2 / TUI substitutes aircraft, which saves the flight but costs hours

How do hand luggage and bags compare on Jet2 and TUI?

Both include 10 kg of hand luggage free. Jet2’s cabin bag is bigger; TUI’s included package luggage can be heavier.

Hand luggage, free on every booking:

• Jet2: one 56 x 45 x 25 cm bag up to 10 kg, plus a 40 x 30 x 20 cm under-seat bag
• TUI: one 55 x 40 x 20 cm bag up to 10 kg, plus a 40 x 30 x 20 cm under-seat personal item

Same weight, same under-seat allowance, but Jet2’s main bag is 5 cm deeper and 5 cm wider. The practical trap runs one way: a case bought to Jet2’s limit will fail TUI’s 20 cm depth. If these are your two airlines, buy luggage to 55 x 40 x 20 cm and it passes both sizers. Both airlines will hold-stow oversize or excess hand luggage at the gate, TUI “may” charge for it, and Jet2 charges £45 / €55 for genuinely extra or oversized bags.

Checked luggage is where TUI’s package machine shows. Fly TUI Airways both ways on a package and at least 20 kg per person is included, rising to 25 kg for TUI BLUE, Holiday Villages, River Cruise, wedding, and Premium bookings, with pooling allowed across the booking up to 25 kg per bag. Jet2holidays packages include 22 kg. Flight-only flips the table: neither includes a bag, Jet2 sells 22 kg bags at variable prices, and TUI’s no-allowance airport rate is a steep £60 / €70 per 15 kg bag short-haul (£80 / €90 long-haul and to a handful of destinations). Either way, add luggage online, never at the airport.

Winner: hand luggage size

Jet2 / 56 x 45 x 25 cm vs 55 x 40 x 20 cm, both 10 kg

Winner: included package luggage

TUI / 20-25 kg vs Jet2's 22 kg; TUI's 25 kg tiers win for divers and long stays

Winner: flight-only bag costs

Tie / neither includes one; both punish airport purchases

Package holidays: Jet2holidays or TUI?

Jet2holidays is now the UK’s biggest tour operator and the Which? Recommended Provider. TUI is the global giant with exclusive hotel brands and cruises.

This is the real contest, because both companies sell far more holidays than seats. Jet2holidays passed TUI to become the UK’s largest tour operator, and it did it on the same formula as the airline: 22 kg bags, transfers included, ATOL protection, and customer service that wins surveys. The brand’s Which? Recommended Provider status spans both the airline and the holidays arm.

TUI’s strength is vertical integration that Jet2 cannot match. It owns hotel brands (TUI BLUE, RIU partnerships, Holiday Villages, Sensatori), a cruise line (Marella, with 20 kg luggage and bonded transfers on cruise packages), and river cruises, and its packages ladder up to 25 kg included luggage. When the product is “a TUI hotel,” the airline comes with it, delays and all.

For a like-for-like beach week in Majorca, Jet2holidays is the stronger default: better airline, equal protection, and the satisfaction data on its side. For a Marella cruise, a Sensatori all-inclusive, or anything long-haul, TUI is selling something Jet2 does not stock.

Winner: short/mid-haul packages

Jet2 / better airline under the same kind of package

Winner: exclusive hotels and cruises

Where do Jet2 and TUI fly?

Similar short-haul maps, then TUI keeps going: 787s to the Caribbean, Mexico, Florida, and the Indian Ocean.

Short and mid-haul, the two networks blanket the same holiday geography: Spain, the Canaries, the Balearics, Greece, Turkey, Cyprus, Portugal, Egypt, plus ski. Jet2 flies roughly 80 destinations from 14 UK bases, including 29 routes from its new Gatwick base for summer 2026; TUI flies from over 20 UK airports with a similar Mediterranean spread, and both reach deep into regional airports the legacy carriers ignore.

The separation is long-haul. TUI Airways operates Boeing 787 Dreamliners to Jamaica, Mexico, the Dominican Republic, Florida, Cape Verde, and the Indian Ocean, almost entirely as package and cruise feeders. Jet2 has no long-haul program at all; its fleet of 737s and new A321neos tops out around the Canaries and Egypt. TUI also flies year-round more broadly on winter sun routes, where parts of Jet2’s map go quiet outside summer.

Winner: short-haul leisure coverage

Tie / both blanket the same sun map from UK regional airports

Winner: long-haul

TUI / 787s to the Caribbean, Mexico, Florida; Jet2 has none

Who Should Pick Jet2

• Your holiday is short or mid-haul and you want the airline with 68 percent punctuality, not 59.2
• You want the bigger free cabin bag: 56 x 45 x 25 cm against TUI’s 55 x 40 x 20 cm at the same 10 kg
• You are booking a package and want the operator that currently tops the satisfaction tables, with 22 kg bags and transfers included
• A delay would wreck a tight itinerary: TUI’s aircraft-substitution model trades cancellations for hours of waiting
• You fly from the North, Midlands, or Scotland, where Jet2’s bases are densest, or want the new A321neos at Gatwick
• You are flying flight-only and value free allocated seating at check-in

Who Should Pick TUI

• The trip is long-haul: Caribbean, Mexico, Florida, Cape Verde, or the Indian Ocean on TUI’s 787s
• You are booking a Marella cruise or a TUI-exclusive hotel (TUI BLUE, Sensatori, Holiday Villages), where the package only exists at TUI
• Your package tier includes 25 kg luggage and you will use every kilo
• “Definitely flying, possibly late” beats “small risk of cancellation” for your nerves; TUI’s 0.21 percent cancellation rate reflects a genuine never-cancel culture
• You want winter sun on routes where Jet2’s seasonal map has gone quiet
• Your local airport is one TUI serves and Jet2 does not

The Bottom Line

On the ground these two companies look like twins: UK package-holiday specialists with included bags, transfer coaches, and ATOL protection, fighting over the same beaches. In the air they are not twins. Jet2 runs the most reliable short-haul operation in the UK and tops the satisfaction tables; TUI Airways spent 2025 as the country’s most delayed major airline, nearly nine percentage points behind. When both sell the same week in Crete, that gap is the whole decision.

TUI’s case is its catalogue, not its cockpit. Dreamliners to Montego Bay, cruise-and-stay around Marella, hotel brands you cannot book through anyone else, and 25 kg luggage tiers on its premium packages. None of that has a Jet2 equivalent, and for those trips TUI remains not just the better choice but the only one of the two.

The screenshot version: if Jet2 flies it, fly Jet2. If the dream is long-haul or a cruise, TUI has the monopoly between these two, so pad the schedule and pack the patience. For how Jet2 compares against the budget pure-plays, see Jet2 vs easyJet and Jet2 vs Ryanair.
