Frontier Airlines has reduced its second-quarter capacity, withdrawn full-year guidance and warned of a first-quarter loss, citing an “uncertain” and “weakened demand environment”. The US carrier’s parent company, Frontier Group, says in a 10 April filing with the Securities and Exchange Commission (SEC) that revenue growth in the first quarter is anticipated to be lower than expected due to weaker demand in March. In response to a “weakened demand environment”, Frontier has cut scheduled capacity in the second quarter by a “low single digit” amount, compared with the same period last year. The Denver-based airline says it will “closely monitor the demand environment and make any further adjustments to capacity and related costs, as appropriate”. Frontier expects to report a net loss in the first quarter, which it says will result in a loss per share of between 20 cents and 24 cents. It adds that it is unable to reaffirm full-year guidance for 2025 “due to the uncertain environment”, having previously forecast adjusted earnings per share for 2025 of “at least” $1. This follows an announcement from Delta Air Lines earlier this month that it does not expect to raise capacity in the second quarter because of “broad economic uncertainty around global trade”. The US major said that growth had “largely stalled”, and did not provide any updated guidance for the full year. The US government has announced that it will bring in a range of steep tariffs on imported goods from other countries. The changing nature of those tariffs and the planned introduction of countermeasures by other countries have created uncertainty in global markets. Frontier will release its first-quarter financial results on 1 May.

Neste has begun producing sustainable aviation fuel (SAF) at its refinery in Rotterdam in the Netherlands, as part of its plan to significantly expand SAF supply in Europe. The Finland-based renewable fuels specialist has modified its Rotterdam facility to produce up to 500,000 tonnes of SAF each year, which it says will increase its global SAF production capability to 1.5 million tonnes annually. Neste aims to produce 2.7 million tonnes of SAF and renewable diesel each year at the Rotterdam refinery from 2027. It envisages that its total annual SAF production capability by this point will be 2.2 million tonnes. The company also has refineries in Singapore and in Porvoo, Finland. "Our SAF production capability, now also in Rotterdam, enables us to significantly contribute to the implementation of the ReFuelEU Aviation Regulation and similar SAF mandates," states Neste chief executive Heikki Malinen. "Policies like these are crucial to ramping up SAF production and usage, and we need to keep our ambitions and targets high."

Intelsat's multi-orbit satellite-based in-flight connectivity solution will be available as a line-fit option on Embraer E-Jet E2 aircraft, following a final agreement announced by the two companies during the Aircraft Interiors Expo in Hamburg. The solution uses Intelsat's geostationary (GEO) satellite network and Eutelsat OneWeb's low-Earth orbit (LEO) satellites to provide what the company says is high-speed, low-latency in-flight connectivity. It incorporates an electronically steered array (ESA) antenna, which switches between GEO and LEO satellites to provide the best coverage at any given time. The Intelsat ESA will be available as a line-fit option by the end of this year. "Passengers on Embraer E2 aircraft will soon enjoy the same high-speed internet access from the clouds that they enjoy at home, thanks to our wide coverage and low latency," states Intelsat director of OEM programmes Rob Baird. Martyn Holmes, chief commercial officer at Embraer Commercial Aviation, adds: "Factory-installation of the Intelsat ESA is a good example of how we're making it easier for our customers to offer an improved passenger experience as soon as the aircraft is delivered. "Reliable, high-speed connectivity is a key opportunity to significantly improve passengers' onboard experience – helping to keep airlines competitive and their passengers productive and entertained in flight."
