Pete Buttigieg Left 'Speechless' After Airlines Sue Biden Administration Over New Fees Regulations

May 14, 202418:08 PDT

DAL−0.75%

AAL−1.00%

UAL+0.02%

JBLU−0.08%

Major airlines have initiated a lawsuit against a new rule that mandates them to disclose additional fees upfront. This action has elicited a strong reaction from Transportation Secretary Pete Buttigieg.

What Happened: The lawsuit was launched by Airlines for America, a trade association, and several major airlines, including Delta Air Lines DAL, American Airlines AAL, United Airlines UAL, JetBlue Airways Corp. JBLU, Hawaiian Airlines HA, and Alaska Airlines ALK, reported The Hill.

The airlines are contesting the new rule, arguing that revealing extra fees before ticket purchase will “greatly confuse consumers” and “complicate the buying process.”

Buttigieg, however, expressed astonishment at the lawsuit, stating, “We just issued a rule requiring airlines to inform you, before you buy a ticket, of fees they will charge you. Now, the airline lobby is suing us, saying that if you have the right to that information it will ‘confuse' you. For once, I am speechless."

The Department of Transportation has pledged to “vigorously defend” the rule, which is intended to protect consumers from “hidden junk fees” and ensure full price transparency before ticket purchase.

The Biden administration finalized the rule last month, with Buttigieg asserting that it will save passengers over half a billion dollars a year in unnecessary or unexpected fees.

Why It Matters: This lawsuit comes after a series of confrontations between the airlines and the Biden administration. The Biden-Harris Administration had previously enforced a rule requiring airlines to swiftly issue automatic cash refunds to passengers.

In May it was reported that the Biden administration demanded that airlines disclose, upfront, the fees that they impose on fliers.

Power-On Reset (jacobsa.github.io)

S2 booted from SD card beeglebone black circuittry page 268

On power up, these pins are read by the processor to determine the boot order. S2 is used to change the level of one bit from HI to LO which changes the boot order.

Always Boot from SD Card

"...move R68 to R93 if you want to make the board boot from SD by default."

ref: https://stackoverflow.com/questions/33030802/fix-the-boot-order-emmc-on-a-beagle-bone-black

A latching switch would be nice. Onboard flash is built in obsolescence.

Instructions

Put some leaded solder on both sides of R68 (bottom of board, the silkscreen is misplaced, but just count down the line). Use hot air to remove R68, being careful not to use too much air flow which will knock the resistor off your bench, onto the floor. The resistor is a 100K, in case you lose it.

After removing the resistor, use an iron to put small dobs of leaded solder on pad R93 (top side of board). Use hot air to heat the board until the solder is fluid, then place the 100K R onto R93, heating as necessary while being careful not to blow the resistor away.
